Cytec Engineered Materials 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).* Composites can be used in lightly loaded applications at temperatures up to 500°F (260°C) due to the semi-crystalline nature of the polymer. The composites possess excellent environmental resistance, toughness and fir resistant properties.
APC-2 prepreg can be stored at ambient conditions and has an indefinite shelf life. APC02 composites retain good mechanical properties at cryogenic temperatures. The excellent composite properties result from the PEEK matrix, the 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 from autoclave consolidation to rapid stamping techniques. The prepreg may also be filament wound and tape-placed using in-situ consolidation. This wide range of processing techniques may be used because of the thermoplastic nature of the polymer and the full wetting of the fibers in the prepreg.
