Abstract: A method and apparatus for manufacturing a formed article of a composite material. The formed article is manufactured by heating and pressurizing a thermoplastic resin material and fabric material. The method includes a preforming process in which the material to be formed is put in a preforming mold with a release sheet arranged between the material and a part of the preforming mold. The material is heated and pressurized to impregnate the thermoplastic resin material into the fabric material, thus forming an impregnated intermediate material. Then, in a transport process the impregnated intermediate material in a heated state is taken out from the preforming mold with the release sheet left attached thereto, and transported. Finally there is a forming process in which the impregnated intermediate material is accommodated in the forming mold and the impregnated intermediate material is formed into the formed article of the composite material by pressurizing.

Abstract: A molding method for a composite sheet used for manufacturing a thermosetting resin prepreg sheet in which a thermosetting resin material is impregnated into a fiber sheet includes: bringing a resin transfer sheet in which the thermosetting resin material of a predetermined thickness is carried on one surface of a transfer sheet into contact with one surface of the fiber sheet to be stacked on the fiber sheet. The resin transfer sheet and the fiber sheet in the stacked state are subjected to a heating treatment or heating and pressurizing treatment. The resin transfer sheet and the fiber sheet in the heated and stacked state is subjected to a cooling treatment or cooling and pressurizing treatment so that the thermosetting resin material is transferred to the fiber sheet and the thermosetting resin material is made to adhere to one surface side of the fiber sheet.
