PURPOSE: To obtain a laminated sheet having a favorable surface form, by a method wherein prepregs are arranged between metallic plates, which are most close to a hot platen, so that a surface-treated resin film is placed between the prepregs, a caul produced by piling up a metallic foil on the prepreg, heating and press-molding is arranged and a pressed body is heated and press-molded. CONSTITUTION: A pressed body 4 comprising a prepreg 2 and metallic foil 3 is constituted between metallic plates 1, 1 forming a pair. A plurality of the pressed bodies 4 placed between the metallic plates 1, 1 forming a pair are arranged between a pair of hot platens 5, 5. Furthermore, a top and bottom hot platens 5, a caul 7 obtained between the metallic plates 1 which are most close to the hot platen 5 and further a cushioning material 8 on the hot platen 5 side are arranged, after heating and press-molding.cooled under the same pressure and a laminated sheet is molded. Hereby, when thermosetting resin of the prepreg 2 constituting the pressed body 4 is hardened, a thermoplastic resin film is melted and stress to be generated when the pressed body 4 to be heated and press-molded close by the hot platen 5 performs hardening and contracting/cooling and contracting can be absorbed by the caul 7. |
