８−３３３０２号公報参照）。[Prior Art] Generally, as this type of reflecting mirror, a sheet metal sheet made into a curved shape or a synthetic resin made into a curved shape in the same way are used, but these have a high strength against local compression. It has the disadvantage of lacking sexiness. In order to solve this problem, an anti-D4 mirror has been developed in which a synthetic foam material is filled between a pair of aluminum alloy plates and a synthetic resin is filled in the voids between the synthetic foam materials (Japanese Patent Laid-Open Publication No. 5
8-33302).

It is built. Composite materials manufactured by this method are called sandwich steel sheets, and their structure is simply a flat plate with a resin layer formed between metal plates, and can be shaped by bending or drawing. It's not a thing.

案した（特願昭６３−１１８７３号）。Therefore, the inventors of the present invention have proposed a method for manufacturing 'g1 base materials of various shapes by combining sheet metal press working and resin injection molding (Japanese Patent Application No. 61-224223; No. 62-211322). In other words, in these manufacturing methods, two metal plates to be molded are placed in a stacked state between a pair of movable molds with uneven parts such as bamboos and dies for press working, and a fixed mold. do. After that, the movable molds are moved to clamp the molds, and press working is performed first.Then, with one metal plate held in each mold, the movable molds are moved back in the direction of releasing the clamping, and both A cavity of a predetermined width is formed between the metal plates, or a cavity is formed on the outside of the metal plate through a hole formed by press working, and a molten resin is injected into the cavity to form a resin layer. After the resin layer is cured, the composite molded product is taken out. In addition, as another manufacturing method for composite materials, there is a manufacturing method in which two molded plates are separated and pressed simultaneously, and a resin layer is formed between the two molded plates that have been pressed in the separated state. At the same time, we also proposed a mold for the molding (Japanese Patent Application No. 11873/1983).
