Solvay’s APC -2 composites have a thermoplastic matrix of poly(ether-ether-ketone) commonly referred to as PEEK. The polymer is semi-crystalline with a glass transition temperature of 289°F (143°C). The composites possess excellent environmental resistance, toughness, and fire resistant properties.
APC-2 prepreg can be stored at ambient conditions and has an indefinite shelf life. APC-2 composites retain good mechanical properties at cryogenic temperatures. The excellent composite properties result from the PEEK matrix’s full wetting and tailored fiber matrix interface achieved in the impregnation process.
Laminates and parts can be fabricated from APC-2 using a wide range of processes including autoclave consolidation, rapid stamping techniques, and automated lay down including in-situ.
Typical applications for Solvay’s APC-2 include aircraft and space structure, and other structural engineering components.
