APC2 PEEK THERMOPLASTIC POLYMER DESCRIPTION Cytec Engineered Materials APC2 composites have a thermoplastic matrix of poly(etheretherketone) commonly referred to as PEEK. The polymer is semicrystalline 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 semicrystalline nature of the polymer. The composites possess excellent environmental resistance, toughness and fir resistant properties. APC2 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 APC2 using a wide range of processes from autoclave consolidation to rapid stamping techniques. The prepreg may also be filament wound and tapeplaced using insitu 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. FEATURES & BENEFITS Semicrystalline, thermoplastic matrix Fully impregnated, unidirectional prepreg Large database Very high toughness and damage tolerance Tg of 289 F (143 C). Service temperature up to 500 F (260 C) depending on stress conditions* Excellent environmental resistance Good resistance to creep and fatigue Outstanding fire resistance Very good wear resistance Processed using a wide range of fabrication techniques at 720 F (382 C) Indefinite shelf life at ambient conditions SUGGESTED APPLICATIONS Typical applications for Cytec Engineered Materials APC2 include aircraft structure, space components and other structural engineering components * NOTE: Tg data is not applicable for U.S. export control classification or licensing.
