Abstract

PURPOSE:To facilitate molding, raise the rigidity and reduce the weight, by laminating a resin-impregnated fiber sheet with nets made of a light metal having a high rigidity such as aluminum and by molding the laminated members while heating them. CONSTITUTION:The sheet 2 made of reinforced fibers or pulp fibers impregnated with epoxy resin, phenolic resin or alkyl resin are laminated with the nets 1 made of aluminum, aluminum alloy or aluminum treated with boron. Then, the laminated members are molded while heated. The resin impregnated in the fiber sheet 2 is molten to couple the metal nets 1 thereto. Thus, a vibrating plate 3 of predetermined form 3 is produced.
