Abstract
A carbon fiber coated with 0.3 to 10 wt. % of a polyurethane resin is disclosed. Also disclosed is a carbon fiber reinforced thermoplastic resin composition consisting preferably of 3 to 60 wt. % of such carbon fiber and 97 to 40 wt. % of a thermoplastic matrix resin. Said carbon fiber has increased gathering properties and adhesion strength to facilitate the mixing with the thermoplastic matrix resin and provides a resin molding having improved mechanical properties, especially increased impact strength.
