ABSTRACT:
A mold for molding a composite article has an upper half mold, a lower half mold having a base and a core mounted on the base, and a pressure plate. A plurality of holes are formed in the upper surface of the pressure plate, and springs are placed in the holes. A laminated sheet formed by laminating woven fabrics is placed on the core, and the pressure plate is put on the laminated sheet so as to press a part of the laminated sheet against the core by its weight without creasing the part of the laminated sheet. When joined to the lower mold, the upper mold compresses the springs to compress the part of the laminated sheet firmly between the pressure plate and the core, and then bends the laminated sheet along the side surfaces of the core so that the laminated sheet is shaped in a predetermined shape.
