VIAM, the Central Russian Materials Research Institute for Aviation Engineering, has given Fortron polyphenylene sulfide (PPS) clearance for take-off.
A panel of experts confirmed the polymer's high-performance properties meet stringent aerospace standards. This opens the way for Russian aviation industries to specify Fortron PPS from Ticona, Summit, N.J., in hybrid metal-to-plastic assemblies and other uses where weight and cost carry a premium.
Airbus in France has also used Fortron PPS in both interior and exterior aircraft components for years. Glass-fiber composites based on Fortron PPS help cut costs radically in the new Airbus A380 aircraft. Designers specified PPS in over 1,000 parts. Use of the material reportedly cut costs by as much as 30% and gleaned 50% weight savings.
Traditional metal and light-alloy components will increasingly be replaced by the semicrystalline polymer in applications ranging from seats, equipment components, and assemblies to wing sections, vertical tail and rudder units, and fuselage-reinforcing elements. Fortron PPS meets stringent standards for inherent flame retardancy, high chemical resistance, and good dimensional stability. It also offers high hardness and rigidity and excellent oxidation resistance.
