Abstract
A composite molded article which is produced by joining multilayer boards composed of fiber-reinforced thermoplastic resin onto the surface of a core material made of a foamed resin, and its production method. The composite molded article is constituted by a core material which is composed of a foamed resin molded into a desired shape, and the multilayer boards 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 the direction of the reinforcement fiber being different with respect to each other, and are heated to not less than a melting temperature of a thermoplastic resin contained therein so as to mutually glue the prepregs, and to remove air contained inside. When the composite molded article is produced, the multilayer boards having been molded into shapes adapted to a shape of the core material are heated to not less than the melting temperature of the thermoplastic resin and are pressed and glued to the core material to make the composite material article.
