PURPOSE: To manufacture the captioned material having an excellent performance with high productivity by shaping a compound sheet made integrally of long carbon fiber foil and thermoplastic resin above a melting point and a softening point of this resin and below its decomposition temperature and subjecting it to cooling process.
CONSTITUTION: A compound sheet made integrally of a cloth foil-shaped substance, i.e. a clothlike material consisting of strands of bundled carbon filaments, a mat- shaped substance of continuous long fiber and thermoplastic resin such as styrene resin, acrylic resin, etc., is shaped into a desired form above a melting point or a softening point of this thermoplastic resin and below its decomposition temperature. Next, it is cooled and manufactured into a carbon fiber-reinforced thermoplastic resin formed product. The cloth foil is reinforced by glass fiber, metallic fiber, polyamide fiber, etc. While the thermoplastic resin can be added with various additives such as heat resisting agent, lubricant, coloring agent, short fiber-shaped reinforcing fiber, etc. for property improvement.
