CARBON-FIBER-REINFORCED THERMOPLASTIC-RESIN COMPOSITE MATERIAL AND MOLDED BODY USING THE SAME

摘要

The invention is intended to obtain a composite material suitable for mass production or the like by shortening the molding time while obtaining the advantages of the composite materials described above, and intended to provide a composite material which has a short molding time by the use of a thermoplastic resin as a matrix and is excellent in balance among stiffness, strength, and thermal conductivity. A carbon-fiber-reinforced thermoplastic-resin composite material comprising: a layer (I) containing a carbon fiber (A) aligned in one direction and a thermoplastic resin (C-1); and a layer (II) containing a carbon fiber (B) aligned in one direction and a thermoplastic resin (C-2), wherein the carbon fiber (A) has a higher elastic modulus than the carbon fiber (B).
