发明名称 Molded resin laminate and method for producing the same
摘要 A molded resin laminate in which the dimensional accuracy and the strength are excellent at a bent portion and a method for producing the same are provided. One, in which an average diameter of small cells existing in a region on a side of a resin cover to be formed into a surface layer is smaller than an average diameter of large cells existing in a region on a side of a base resin component to be formed into a base layer, is used as a foamed resin component to be formed into an intermediate layer of the molded resin laminate. After the base resin component is molded with a molding machine, the base resin component is held on a male mold of a forming machine different from the molding machine described above. A sheet-shaped laminate, which is obtained by joining the foamed resin component and the resin cover, is arranged between the base resin component and a female mold. Subsequently, the forming machine is subjected to mold clamping. The sheet-shaped laminate and the base resin component are joined to one another in a cavity, and the gas in the cavity is vacuum-evacuated to thereby form the sheet-shaped laminate.
