    • PURPOSE:To stably and efficiently obtain a composite material the surface of which is roughened by the exposure of a fiber base material by laminating a thermoplastic resin film to prepregs to heat the whole under pressure not only to soften the thermoplastic resin film but also to cure the resin of the prepregs and subsequently peeling the film to form a rough surface to the prepreg composite. CONSTITUTION:For example, two prepregs each formed by impregnating a fiber base material composed of a glass fiber fabric with a 120 deg.C curable expoxy resin and thermoplastic resin films 2 each composed of a polyethylene film with softening temp. of about 90 deg.C and an m.p. of 110 deg.C are laminated to the upper and rear surfaces of the obtained prepreg laminate and the whole is heated at 120 deg.C while pressed by the molding plates 4 of a hot press to be subjected to laminate molding. After molding, the polyethylene films 2 are peeled. That is, when the prepreg laminate is heated along with the thermoplastic resin films, the fiber base material of the prepregs is held to a hard state but the resin thereof is fluidized and the transfer surface of the surface shape of the fiber base material is formed on the surfaces of the thermoplastic resin films.
