PURPOSE: To improve impact resistance and miscibility with resins, by coating a metal-coated carbon fiber with a completely thermoplastic polyurethane resin.
CONSTITUTION: A metal-coated carbon fiber is coated with a completely thermoplastic polyurethane resin. Pref. the metal-coated carbon fiber is coated with 0.3W10wt% polyurethane resin. When the quantity of the resin is less than 0.3wt%, the ability of the fiber to form a bundle is poor and the adhesion between the fiber and the resin is not so much improved, while when it exceeds 10wt%, the bundle forming ability is too high to disperse the fiber and the strength is lowered. Pref. 5W70wt% metal-coated carbon fiber coated with 0.3W 10wt% polyurethane resin is blended with 95W30wt% thermoplastic resin.
