PURPOSE:To reduce the number of molding processes and to improve productivity by pressing, heating and adhering a layered raw material prepd. by positioning a foamed layer on a core material layer incorporated with a thermosetting resin and positioning a skin layer on the foamed layer. CONSTITUTION:A layered raw material 11 consists of a core material layer 12, a foamed urethane layer 13 and a skin layer 14. The core material layer 12 is obtd. by impregnating a non-woven fabric with a thermosetting resin such as a phenol resin and an epoxy resin. When the layered raw material 11 is pinched and pressed by means of a core mold 15 and a cavity mold 16, the thermosetting resin contg. the non-woven fabric is molded and cured and at the same time, molding if the foamed urethane layer 13 with a thickness distribution corresponding to the mold is simultaneously performed by heating and pressing. A molded item is obtd. by pressing while heat conducted from the core mold 15 is kept so as to obtain a uniform surface temp. by cooling the cavity mold 16. Side edge parts of the core material 12 and the skin layer 14 of a molded item 20 are tightly adhered by pressing to obtain the molded item 20 wherein the foamed urethane layer 13 is not exposed outside. |
