HexTow® Chopped Fiber0 pages

 
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.
Addition of chopped 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.
