COMPOSITES EUROPE 2010 is organised by Reed Exhibitions in partnership with the European composites industry association EuCIA and Reinforced Plastics magazine. The International AVK Conference runs alongside the exhibition on 13-14 September. In this preview we take a look at what exhibitors will be highlighting during the show. (Companies are listed in alphabetical order.)
3A Composites Core Materials
Stand number G56, Hall 10-11
3A Composites Core Materials will present the world of core materials and its well-known brands AIREX® and BALTEK®. 3A Composites Core Materials (formerly known as Alcan Composites Core Materials) will exhibit at COMPOSITES EUROPE 2010 together with its German distributor Gaugler & Lutz.
The company will present its DRIVEN by ECO-LOGIC and the Hybrid Core Concept® with the Hybrid Core Calculator.
3A Composites says its Hybrid Core Concept® comprises the widest portfolio of core materials, the necessary know-how and the toolset that allow customers to tailor their sandwich solution to ultimate performance. Based on three different optimisation – criteria which are price, properties and sustainability – the optimal sandwich design can be calculated with the Hybrid Core Calculator. A life cycle analysis (LCA) shows the total environmental impact of a product throughout the different phases of a product‘s life cycle. Each phase of the life cycle consumes resources and may generate reusable output (recycling). The sum of all input minus all reusable output is the environmental footprint of a product.
3A Composites Core Materials is a global organisation with operations in Europe, North America, Ecuador and China and is part of 3A Composites, a division of Schweiter Technologies AG.
3B, a manufacturer of glass fibre products for the reinforcement of thermoplastics and thermosets, will showcase its Advantex® and HiPer-tex™products in high performance pressure vessel and ballistic applications at COMPOSITES EUROPE.
“We were extremely pleased to exhibit at Essen," says Hugues Jacqumain, CEO of 3B. "We have much to offer with our Advantex and Hipertex products as well as the unique technical experience we have gained in key, high performance applications. We are looking forward to welcoming customers on our stand and to discussing how we can develop product solutions matching their needs.”
3B's focus at the show will centre on its direct rovings and continuous filament mat (CFM) product lines, including:
- Advantex Direct Rovings SE 1500 used as an input for weaving and knitting operations for higher stiffness and enhanced fatigue performance in epoxy laminates;
- Advantex Direct Roving SE 8400 LS (Low Seeds) specifically developed for composite high voltage electrical insulators rods and designed for pultrusion processes;
- Advantex CFM M8615 used as an infusion media for close mould applications in wind energy turbine blade applications;
- Advantex CFM M8643 for pultrusion processes for wide, long and heavy parts as well as narrow and complex profiles;
- Advantex rovings for high pressure cylinder applications such as CNG (compressed natural gas) cylinders (Advantex rovings are now approved to be used for high pressure vessels that meet ECE110, ISO 11439 and NGV-2 standards); and
- HiPer-tex B15 rovings designed for hard composite armour applications such as composite blast panels, ballistic panels, and spall liners for military and law enforcement vehicles, security vehicles and naval vessels.
Compared to E-glass, 3B reports that HiPer-tex glass fibre delivers overall superior performance: 30% higher strength; 17% higher stiffness; 45% higher strain energy; 10 times greater fatigue resistance; and 30% lower coefficient of linear thermal expansion.
Stand number D08, Hall 10-11
Turkish company AKPA specialises in the production of organic peroxides, initiators and accelerators for the composites and plastics industries. The company is introducing two new products for phthalate free polymerisation systems; AKPEROX® A50-PF and A60-PF are now available to customers worldwide.
Phthalates are widely used as plasticisers in chemicals industry and today they are being phased out of products in many countries, especially in the USA, EU and in Turkey, because of health concerns. For this reason, AKPA offers two new products called A50-PF and A60-PF that can replace existing A50 and A60 grades. There will be no change at gel-cure performance and end products’ characteristics except no phthalate content.
A ‘green’ plastic? What sounds like a contradiction in terms is in fact already part of our everyday lives. PET is 100% recyclable and is fed back into the economic cycle as a high-quality resource. PET beverage bottles, for example, are recycled in the form of polyester fibres which are then used to make products such as fleece textiles or new bottles. Armacell is now able to manufacture foam cores, which are used in transport, wind turbine construction or shipbuilding, from the recyclate of PET bottles.
Armacell is adopting the cradle-to-cradle principle. This concept is aimed at avoiding waste by recycling materials in a closed loop and, therefore, continuously reusing them. However, this recyclability (and thus the conservation of natural resources) is not the only advantage of the polymer. Its low weight makes PET an ideal material for lightweight construction applications. PET foam cores are extremely energy efficient because they require less input power than conventional materials. Furthermore, ArmaFORM PET foams have high mechanical strength in combination with residual flexibility and excellent fatigue resistance. They are also high temperature resistant and withstand short-term curing temperatures of up to +180 °C. They also display very slight variances in density of ±5 kg/m3 and, unlike natural core materials, their availability is ensured.
Typical areas of application for ArmaFORM PET foam cores are marine applications (boat hulls, cabin interiors), transport (carriage body, interior panelling in trains, buses, trucks and cars) and wind turbine construction (rotor blades, nacelles). Whereas the disposal of rotor blades made of conventional composite materials presents problems which will become a real challenge for wind turbine operators in the coming years, PET foams are 100% recyclable.

Stand A23, Hall 12
Whether for automotive interiors or the construction of special vehicles, ships and containers, Collano adhesives are particularly successful when specifications go beyond simple bonding functions. Collano adhesives take on special missions such as noise dampening, absorbing vibration and shocks, equalising joint tolerances and stresses, and stabilising structures, to name just a few. Collano offers a broad range of hot melt adhesive films as well as reactive 1C and 2C adhesive systems.
Collano offers a new spray applicator for 2C PUR and 2C PUR polyurea adhesives. This offers a test platform for customer-specific as well as real-world surface bonding and contour curtaining tests. The Isotherm spray applicator is equipped with a die head and a spray/mix head. Powered by a new hydraulic drive, the high-pressure machine is exceptionally flexible as regards application quantities and mixing ratios. With a variable component mixing ratio from 1:1 to max 4:1 / 1:4, the system guarantees homogeneity and continuity in production.
Hot melt adhesive films developed by Collano are used wherever conventional adhesive systems reach their limits. They are ideally suited for applications in the transport industry (vehicles, aircraft, truck and railway platforms and superstructures, boats and ships, passenger and cabin compartments) and in house construction (interiors, acoustic panels, white boards, furniture, kitchen). Hot melt adhesive films are used in the industrial fabrication of lightweight structural components, honeycomb elements and sandwich panels, including high-performance sandwich structures consisting of foam or honeycomb cores with cover layers of metal or fibre reinforced plastic (FRP). Hot melt adhesive films are clean, can be applied with precision and quickly processed, enable a high degree of automation, and are characterised by excellent environmental compatibility. At the same time, they are sufficiently heat resistant under most circumstances. Optimised final properties can be achieved with minimal application quantities. Because preliminary coating of the substrates
(such as honeycomb and/or cover layers) is possible in many cases, the films offer great flexibility and convenience of use. Among other applications, Collano hot melt adhesive films are deployed in continuous coil coating lines to facilitate durable subsequent rear injection and lamination with various polymers.
Multilayer films are a specialty segment within the Collano hot melt adhesive films range. On the one hand, they allow incompatible substrates to be bonded. On the other hand, they impart additional functionality to composite or sandwich elements: barrier layers that repel undesirable substances, provide sound insulation, or stabilise process phases. Sandwich panel manufacturers often deploy multilayer films to split prelamination and completion into two separate thermal cycles. In most cases, this is not associated with increased costs and improves the reliability of the bond.
Stand number G01, Hall 10-11
COMPOSITE-EXPO – 4th International Specialized Exhibition – will take place on 1-3 March 2011 in Moscow, Russia. It is organised by exhibition company Mir-Expo.

Stand number E29, Hall 12
Epurex Films manufactures thermoplastic films based on polyurethane (TPU films). Under the trade name Platilon® highly elastic TPU films and thermoplastic hot-melt adhesive films are extruded for various applications.
Platilon U films, for example, are used for sewage pipe re-lining, surface protection, and for release films. They have high elasticity and abrasion resistance, are free of plasticiser, UV stablilised and show excellent adhesion to epoxy, glass- and carbon fibres. Multilayer films can serve as barrier against styrene, moisture, light, chemicals and gas.
Platilon H films based on polyurethane, co-polyamide and co-polyester are low-melting adhesive films that allow even bonding. These adhesives in the form of a film can join various components, like textile fabrics or honeycomb structures, and keep exactly the same thickness of adhesive layer over entire roll length. Due to their thermoplastic character adhesion only happens by heating the material – i. e. there is no crosslinking or pot life limitation. Composite materials featureing Platilon H can be separated completely for economic recycling.
Stand number D37, Hall 12
ERBO GmbH is presenting a new suction procedure for five-axis milling machines. ERBO has developed a procedure involving a combination of high pressure suction and custom-made evacuation nozzles for each individual tool, allowing suction directly at the tool tip. Dust and chips are captured directly via a movable joint device that can move along every axis, and are then fed to the high-performance extraction system. Dust and chips require much cleaning of components, particularly when constructing large moulds (for instance, for wind turbine rotors). The surroundings of the machine and the staff are exposed to dust, as are the bearings and guides. Through direct tool tip extraction, the new suction device from Erbo ensures a virtually dust-free environment. Dust and chips can be transported up to 250 m by the high-performance extraction system, to be collected in big bags, dust sacks, containers or presses, and either discarded or recycled.

The modular design concept allows individual configuration to customised requirements, and offers engineered solutions into various industries, such as automotive and aircraft, furniture, footwear and technical textiles.
Stand number E56, Hall 12
US company Fiberforge specialises n thermoplastic composite processing technology. Its flagship product, the RELAY® manufacturing system, enables the affordable production of lightweight advanced composite structures in high volumes. Fiberforge offers technology licensing, application development, and ramp-up production.
Earlier this year, Fiberforge delivered 20 thermoplastic composite aircraft engine brackets for testing and evaluation by Honeywell Aerospace. These high performance brackets are 20% lighter than the existing titanium parts while maintaining part stiffness and all existing interfaces. In production, the parts are projected to reduce system cost through weight savings, cost effective manufacturing using Fiberforge’s RELAY process and a design that establishes a common form factor for use in multiple engine configurations.
The engine brackets are structural components that support several engine components, including hoses, cables, and printed circuit boards via integrated captive hardware. Traditionally fabricated from titanium, these replacement brackets are now comprised of carbon fibre reinforced PEEK thermoplastic tape supplied by TenCate. In order to be included in first quarter 2010 turbofan engine testing and evaluation, these brackets were designed, fabricated and delivered just 23 days after the receipt of order.
“This is an exciting programme for Fiberforge,” reports David Cramer, Fiberforge’s Chief Technology Officer. “Working closely with Honeywell and our suppliers, we are able to demonstrate Fiberforge’s ability to develop, rapidly prototype and manufacture high-performance, high-quality advanced-composite products. This is landmark application for both Fiberforge and for the thermoplastic advanced composites industry in general. It also demonstrates that these materials offer strong potential for lightweighting in aircraft by replacing steel, aluminium and titanium. Our mission is to help customers capture this lightweighting potential to create a competitive advantage in their products.”

Fraunhofer Institute for Chemical Technology ICT
Stand number C33, Hall 12
At COMPOSITES EUROPE 2010, the Fraunhofer Institute for Chemical Technology ICT will display a trunk liner for the Porsche Carrera 4 made using a thermoplastic resin transfer moulding technique. The thermoplastic part weighs up to 50% less than the original aluminium part.
ICT engineers claim that the process is suitable for mass production of up to 100 000 parts a year.
"Our method offers comparatively short production times," states Dieter Gittel, a project manager at ICT. "The cycle time to produce thermoplastic components is only around 5 minutes. Comparable thermoset components frequently require more than 20 minutes."
The Fraunhofer researchers have named the technique thermoplastic resin transfer moulding (RTM) (T-RTM). It is derived from the conventional RTM technique for thermoset composites. The composite component is formed in a single step.
"We insert the pre-heated textile structure into a temperature-controlled moulding tool so that the fibre structures are placed in alignment with the anticipated stress," Gittel explains. "That enables us to produce very lightweight components."
Carbon or glass fibres are generally used.
The next step involves injecting the activated monomer melt into the moulding chamber. This contains a catalyst and activator system. The researchers can select the system and the processing temperature in a way that enables them to set the minimum required processing time.
Another advantage of the T-RTM process is that the cost of the thermoplastic matrix material and the cost of its processing are up to 50% lower than the equivalent costs for thermoset structures.

Fibre composite components are normally made from the basic materials of fibre and resin. KRAIBURG has now developed a product that allows for the integration of a third, elastic material into fibre composite components, without the need for an additional process. Latest tests show that the integration of elastomers in the hard-soft-hard composite improves the damping properties.
Vibration tests were carried out in cooperation with KVB Chemnitz. Carbon fibre reinforced plastic (CFRP) plate 2 featured an integrated elastomer layer of 0.5 mm thickness at the centre of the composite structure. This layer reduces the vibration period by approximately 60%. Such products can for example be used to optimise the vibration behaviour of fast moving robot systems in order to increase the productivity of the machine.
The new product was further studied in ultrasound examinations carried out in cooperation with GMA Augsburg. These tests showed that a 2 mm thick CFRP plate with a 0.5 mm elastomer layer integrated below the top CFRP layer significantly improves the impact tolerance of the plate.
This year Kraiburg will be sharing its Composites Europe stand with Lange und Ritter GmbH.
Stand number C27, Hall 12
KraussMaffei’s Reaction Process Machinery division and Dieffenbacher (DSE) recently agreed to cooperate on sales of systems for high-pressure resin injection (high pressure RTM). The alliance addresses a rapidly expanding market – the use of carbon fibre reinforced plastic (CFRP) parts in the automotive industry.
The two major advantages for customers are the ability of the two alliance partners to supply turnkey solutions worldwide, and the time and effort saved by dealing with a single partner for all the elements of the system.
KraussMaffei notes that high pressure RTM is set to play a key role in producing CFRP parts for the automotive industry and current market demand for components for electric and hybrid cars confirms this trend. This process employs fibre intermediates (woven and nonwoven fabric), which are challenging to handle, and production requires vertical presses where the lower mould element allows gravity-assisted loading and draping of the fabric in the mould. The mould is then filled with epoxy resin or polyurethane using high-precision mixing heads which are docked directly onto the mould. During curing, cavity pressure can be as high as 100 bar.
The two companies will be providing the following expertise to the collaboration:
- Dieffenbacher: hydraulic vertical presses with precise parallel control of the ram;
- KraussMaffei: resin metering systems and mixing heads for epoxy and polyurethane;
- Dieffenbacher: handling systems, cutting, preforming and pressing;
- KraussMaffei: post-mould processing, milling, routing, cutting and tooling.
KraussMaffei and Dieffenbacher will also be working together to develop the process further, for example, shortening the reaction (curing) time. This is important because process time is a critical factor in productivity and return on investment.
KRETZER SCHEREN GMBH
Stand number G58, Hall 10-11
As the use of technical textiles such as Kevlar is increasing. However, these technical fibres are so resilient they make cutting difficult and cause the cutting edge to dull very quickly. The classic way to cut textile fabrics is by using scissors, but standard scissors do not cut glass fibres or other aramids. For this reason, Kretzer designed the TEC X1 and TEC X2 series scissors. TEC X1 is made for fibreglass and light aramids; TEC X2 for heavy aramids. Their stable, durable plastic handles are equipped with a smooth soft-rubber grip, and do not blister the fingers. Models with large loops make it possible to work while wearing gloves.
TEC X contains 8 models per series. The size range runs from 6” to 12”. Kretzer has also expanded the range with a curved blade, all-steel model – the Finny TEC X.
Stand number B23, Hall 12

At COMPOSITES EUROPE 2010, Lectra is presenting its Vector TechTex FX 100 cutting solution for industrial fabrics and composite materials. This new machine enables companies to cut wide pieces and meets the needs of companies looking to diversify their offering by covering a broader spectrum of applications.
"The ability to process a wide variety of industrial fabrics with a single, unique cutting solution is now essential to the survival of many companies," says Alexander Neuss, Managing Director for Lectra Germany, Eastern Europe and CIS Countries. "By extending the range of possible activities open to them with the VectorTechTex FX 100, these companies will be able to target new markets and, consequently, limit the risks tied to a decrease in volumes."
VectorTechTex FX 100 is particularly well-suited to short runs and tight production deadlines. By allowing for wider cuts (up to 2.54 m), and can process a wider variety of pieces, all of varying sizes and shapes, while limiting fabric scraps. Material consumption is thus optimised.
This cutting machine broadens Lectra’s VectorTechTex FX range by extending the variety of materials that can be handled, from carbon prepreg to multi-layer cutting of dry materials such as fibreglass and honeycomb.
The VectorTechTex FX 100 integrates a new feature to vacuum away dust produced during cutting, greatly reducing the dispersal of particles that may affect the health of operators.
The VectorTechTex FX range is also said to enable companies to reduce their energy consumption by 20-30% in comparison with standard cutters on the market. Lectra’s Energy Saver system helps to minimise energy usage by changing the machine’s vacuum power during cutting as needed and according to the fabric processed.
Lectra offers its Vector® cutting solutions with a full range of services to optimise customers’ operations. Lectra’s preventive maintenance plans and service contracts provide continuous, remote assistance. These include monitoring the production tool in real time, looking at such elements as state of operation, and wear on parts and consumables.
Lightweight Structures BV
Stand number E02, Hall 10-11
Lightweight Structures BV, based in Delft, the Netherlands, focuses on product development, engineering and manufacturing of structures for markets where weight reduction is one of the design drivers. One recent project involved the engineering and manufacturing of the first composite bridge deck in the city of Utrecht, the Netherlands, which was installed in April.
The bridge replaces a wooden bridge used for pedestrian and emergency vehicles. It is 12 m long and 5 m wide with a total weight of 7 tonnes and a maximal load of 45 tonnes. The hand rails can bear a horizontal load of 3 kN/m of rail. Lightweight Structures chose balsa core material, glass multiaxials and a polyester resin to manufacture the deck. All parts were vacuum infused by the company and then shipped to the contractor's yard where the bridge was assembled and the wear layers and hand rails were mounted, before final installation in Utrecht. The installation of the bridge took only a few hours.
The project is meant to be the pioneer for further bridge substitution projects in the Netherlands where a number of wooden bridges from the ‘70s will have to be replaced within the next few years. Further potential for these composite bridge decks is seen in Belgium and Germany as well as the USA and Japan.
This is the latest of several composites bridges designed and built by Lightweight Structures BV under its ECOSAFE brand name.

Nidaplast specialises in polypropylene honeycomb core for use in sandwich panels with materials traditionally used in building and construction, like natural stone and concrete. The procedure uses a very thin layer of the raw material. This combination saves on the raw material and creates a lightweight structure.
The use of the nidaplast core in sandwich panels with natural stone can be used in framework and self-supporting structures such as flooring, double flooring and staircases. A 5 mm thick marble skin glued on to a 28 mm thick nidaplast core can bear up to 50 times more load and strain than a 20 mm thick marble panel. The sandwich panels can also be applied vertically for partitions and frontages, and used to create furniture (tables, chairs, etc.).
Nidaplast's range of structural honeycomb cores includes:
- Nidaplast® 8: consisting of honeycomb core, a plastic film and a nonwoven polyester skin;
- Nidapan®: a glass reinforced thermoplastic grid strengthens the structural honeycomb core and is used to lighten and strengthen natural stone;
- NidaFGlass: a fine layer of glass fibre and resin combined with the honeycomb core makes the sandwich structure with natural stone resistant in a damp and corrosive environment;
- NidaGSteel: with a fine galvanised steel skin, this product strengthens natural stone for improved fire resistance.

- Crestapol® 1214, a ‘low shrink’ high performance pultrusion resin; and
- Crystic® Fireguard 75PA Excel, an intumescent fire resistant topcoat.
The Crestabond range of methacrylate structural adhesives are primerless, requiring none or only minimal surface cleaning of the substrates to be bonded, saving both production time and assembly costs. The products are aimed at companies in the bus, truck and rail, construction, marine and wind energy markets which are looking for durable, high performance structural adhesives that can be successfully bonded to a wide variety of composite, metal and plastic substrates.
Crestapol 1214 urethane acrylate resin has been developed for pultruding profiles where there is a requirement for fire resistance, low shrink, high quality surface finish or the need to manufacture larger profiles. Crestapol 1212 and 1214 pultrusion resins can be alumina trihydrate (ATH) filled up to 200 phr to achieve a range of fire, smoke and toxic fumes standards specified for certain building and mass transportation applications. As a result of the low viscosity and high reactivity of Crestapol resins, there is no loss of line speed even when heavily filled.
The Crystic Fireguard 75PA Excel intumescent fire protection topcoat is a product upgrade. The ‘Excel’ version offers better fire retardant properties and handling, yet is still cured with a standard MEKP catalyst. It can withstand a direct flame at a temperature of 700° for over 60 minutes without the laminate behind catching fire.
On the Scott Bader stand visitors will be able to see a composite powerboat bow section and watch four new videos. The Crystic Fireguard 75PA Excel video shows the fire resistance performance of this upgraded intumescent topcoat. There are also three demonstration videos – one showing the correct techniques for the application of the new Crestabond structural adhesives, and two videos of Scott Bader’s recommended ‘best practices’ to achieve a top quality brushed or sprayed gel-coat surface finish.
Representatives from both Scott Bader and Bodo Möller Chemie GmbH, a newly appointed distributor for Germany and Austria, will be available throughout the show to answers questions.
Sika Tooling & Composites
Stand number F17, Hall 10-11
The newest developments from Sika are the three epoxy matrix systems Biresin® CR122, Biresin® CR83 and Biresin® 84.
Biresin CR122 is a non-toxic epoxy system which is mainly used for wet lay-up. It has been approved according to the German Air Ministry, LBA/RHV, guidelines for use in light aircraft, powered gliders and gliders. With its very good mechanical properties it fullfills the demands of the required LBA tests. For example, with correct post-cure a glass transition temperature of over 115°C can be reached. This compares favourably with the 97°C minimum required by LBA/RHV. The system is also approved by Germanischer Lloyd.
The new epoxy system for the vacuum infusion process, Biresin CR83, has been approved by Germanischer Lloyd for use in wind turbines and is also suitable for marine and industrial applications. It has an extremely low viscosity (155-170 mPa.s) and good wetting properties which allow fast infusion with high quality impregnation. Biresin CR83 also has a very low tendency to crystallise, which makes it very suitable for applications where storage in controlled temperature conditions is difficult.
The Biresin CR84 epoxy system is aimed at filament winding. The resin is particularly suited to the filament winding process because of its viscosity characteristics, good wetting and a very long pot life (approximately 10 hours), combined with a low cure temperature (e.g. 70°C for a Tg >80°C). Biresin CR84 system has good wetting properties and is also modified to reduce dripping from the fibres during winding. This ensures both high quality components and a clean working environment. The cured resin is tough and has good elongation to break.
Stand number C13, Hall 12
As well as its braiding technology, Teufelberger will be showcasing its metal-composite connection technology T-IGEL®.
The composite division of the Teufelberger Group specialises in the manufacturing of composite parts and components utilising braiding technology. Composite braiding allows for automated fabrication of complex part geometries at high throughput. The capability to integrate various load transmission elements in the braiding structure led to the development of the hybrid connection T-IGEL. This enables a connection between metal and composite using pins that are tightly bonded to the metal body and extend into the composite. No fibre damage or fibre removal occurs. A simple quality control of the joint is possible.
Over multiple pins in various arrangements, high tensional and torsional forces are conveyed. The application of the pins on stainless steel and aluminium carriers and couplings is fully automated. The interconnection strength is above the level of a structural adhesive joint and the connection is formed faster and at lower cost.
T-IGEL is especially suited for application in highly strained shafts, crash structures, and various structural components. It can also be utilised as a hybrid connection in filament wound structures.
