Technical Fibre Products (TFP) plan to exhibit its nonwoven materials at JEC Americas from 2 to 4 June in Houston, Texas, USA.

TFP will showcase products from its Optiveil, Optimat and Tecnofire ranges and its new, extended range of high performance thermoplastic veils including PPS, PEI, PEEK, polyamide and polyimide. These materials have been developed to improve the mechanical properties of a composite with minimal modifications to the manufacturing process necessary. The veils can be interleaved between reinforcement plies to help improve the interlaminar toughness of a composite structure, increasing resistance to both mode-I and mode-II fracture.

The full range of Optiveil and Optimat materials can help achieve a high quality surface finish whilst imparting surface functionality such as conductivity, EMI shielding and corrosion and abrasion resistance to a composite structure. Other benefits include the use of dielectric nonwovens to prevent galvanic corrosion, which occurs when aluminum or other metals come into contact with carbon fiber in a composite structure. The nonwoven provides a uniform, lightweight barrier between the two materials to isolate them, stopping an electrochemical reaction occurring. In addition, the lightweight veils, from 2 g/m², are a carrier or support for adhesive films.

TFP’s Tecnofire range of fire protection materials will also be on display. These materials deliver passive fire protection at the surface of a composite without compromising the integrity of the structure.
