摘要

The present invention relates to a composite molded article which is produced by joining multilayer boards composed of fiber-reinforced thermoplastic resin into the surface of a core material made of a foamed resin, and its production method. The above-mentioned composite molded article is constituted by the core material which is composed of the foamed resin molded into the desired shape, and the multilayer board which are produced such that a plurality of prepregs containing reinforcement fiber by a volume content of not less than 30% and not more than 85% are laminated with changing the direction of the reinforcement fiber, and heated to not less than a melting temperature of a thermoplastic resin contained therein so as to mutually glue the prepregs, and air contained inside is removed. When the composite molded article is produced, the multilayer boards having been molded into shapes adapted to a shape of the core material and heated to not less than the melting temperature of the thermoplastic resin are pressed and glued to the core material to make integration.
