摘要 PURPOSE:To enable a molten resin to be easily fed between fibrous sheet layers even in molds formed into a complicate configuration, and to enable molded products of various shapes to be uniformly reinforced by opening the molds at the start of feeding the molten resin, clamping top and bottom forces prior to the completion of the feed of the molten resin or simultaneously with completion of the feed of the same, and then performing molding under pressure. CONSTITUTION:A plurality of porous fibrous sheets are set in a superposed state between a top force and a bottom force 2 having a molten resin passage 7 therein, and the top and bottom forces are clamped. The periphery of a hole provided in the porous fibrous sheet 4 on the side of a molten resin feed port 6 is brought into contact with the periphery of the molten resin feed port 6 and, in the case where a molten resin 5 is fed between porous fibrous sheet layers through the hole, the molds are opened at the start of feeding the molten resin 5 and, prior to completion of the feed of the molten resin 5 or simultaneously with completion of the feed of the same, the top and bottom forces are clamped to perform molding under pressure. Accordingly, a molded product with an extremely remarkable reinforcement effect can be obtained without causing any warping, deformation and the like of the molded product. Furthermore, by applying a discontinuous single-fiber sheet to the outermost layer, a molded product whose resinous surface has a smooth and beautiful appearance can be obtained.
