AIREX T92 is a reformulated and “significantly improved” core material based on Alcan Composites’ PET foams AIREX T90 and T91 introduced in 2005, used in a range of products such as wind turbine blades, trains, boats and industrial applications.

The AIREX T92 will replace AIREX T91 and be used for a wide range of structural sandwich applications. The second generation core material is aid to be lighter while being stronger and stiffer than the T91.

According to Alcan Composites, the real break-through, however, is the increased shear elongation and therefore damage tolerance. With a shear elongation at break of 15%, AIREX T92 offers an increased damage tolerance “in the range of well proven PVC [polyvinyl chloride] foams.”

It is compatible with all common resins and production processes up to 150ºC showing neither shrinking nor out-gassing.

AIREX T92 will be available as rigid sheets and also with the conventional sheet finishing options for good sheet contourability and/or resin infusion properties. Besides the standard format of 610 mm x 1220 mm AIREX T92 can also be delivered in large sheets of 1220 mm x 2440 mm.

Alcan Composites brands its PET foam as a green product that can be fully recycled, and the CO2 used as blowing agent is a by-product of another production process.
