Properties and Processes of Linear Polyphenylene Sulfide (PPS) for Continuous Fiber Composites Aerospace Applications 2009-01-3242

Linear Polyphenylene Sulfide (PPS) is used in production for a variety of automotive and industrial applications. It exhibits a combination of high temperature performance, creep resistance, excellent dimensional stability and chemical resistance, and flame resistance. Recently, the material is being used in continuous reinforced composites for aerospace applications. The FST performance (flammability, smoke and toxicity), combined with the relatively low cost for this resin make it uniquely qualified for a number of interior applications such as high temperature ducting, seat frames, and interior panels, etc. The use of PPS for thermoplastics composites has been successfully demonstrated in production for critical aerospace components on Airbus A340 and A380 aircraft, and it is finding applications on a number of aircraft interior applications.
PPS composites offer a green product as compared to both thermosets and metal. When compared to thermosets, process energy requirements are substantially less for thermoplastic composites. PPS does not release VOC's in the fabrication process, process scrap is reduced for PPS, and the end product is fully recyclable.
The paper will discuss the basic properties of PPS continuous fiber composites as they relate to aircraft applications and other thermoplastics used in composites, including polyether ether ketone and polyether imide. Thermoplastic composites manufacturing processes and specific applications will be discussed in detail.
