Chopped Fiber

HexTow® Chopped Carbon Fiber

HexTow® chopped carbon fiber is used in compression and injection molding compounds to produce machine parts, gears and chemical valves. The finished products have excellent corrosion, creep and fatigue resistance, plus high strength and stiffness characteristics.

Chopped fiber is used in compression and injection molding compounds to produce parts as varied as machine parts, gears and chemical valves. The finished products exhibit high strength and modulus, excellent fatigue and creep resistance, low thermal expansion, electrical and thermal conductivity, excellent friction and wear resistance, and low shrinkage.

HexTow® PAN-based carbon fiber is available in 1/4 inch chopped fiber lengths, sized for compatibility with various resin matrix systems and processes. The chopped product is small, thin, rectangular flake, 1/4 inch long by 1/8 to 1/4 inch 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.
