PPS Composite Slashes Weight in Aircraft Seats

A PPS-based thermoplastic composite is now being used as a lightweight replacement for aluminum in aircraft seating.

A PPS-based thermoplastic composite is now being used as a lightweight replacement for aluminum in aircraft seating. The seats are pressure formed of Tepex composite sheet made by Bond-Laminates GmbH in Brilon, Germany, from up to 20 layers of woven fabric consolidated in a dual-belt press. Seating elements—lumbar and thigh supports, armrest table covers, and shields for in-flight video screens—contain 60% to 70% carbon fiber reinforcement and provide a 40% to 50% weight reduction and 20% to 25% cost saving versus aluminum. The lumbar support at the base of the seat measures 6.3 x 11.7 in. and weighs about 150 g (5.3 oz). The parts are molded between rubber and metal tools by DTC, Lelystad, the Netherlands. Tepex composite sheet comes in thicknesses of 0.2 to 5 mm. The flame-retardant PPS composite is based on Fortron resin from Ticona, Florence, Ky.
