Hexcel® HexTow™ 1900/AS Chopped Fiber

HexTow™ PAN based carbon fiber is available in 1/4 in. chopped fiber lengths, sized for compatibility with various resin matrix systems and processes. The chopped product is small, thin, rectangular flake, 1/4 in. long by 1/8 to 1/4 in. wide. The individual filaments are lightly held together by the sizing, and will break apart during subsequent processing.The specially formulated sizing systems, in addition to improving bonding, produce a higher bulk density that aids in blending operations and in the flow through mechanical feed systems.Addition of carbon fiber to molding compounds produces a material that exhibits high strength and modulus, excellent fatigue and creep resistance, low thermal expansion, electrical and thermal conductivity, excellent friction and wear-resistance, and low shrinkage.Information provided by Hexcel
