PURPOSE:To improve adhesive strength and appearance by interposing a hot melt type adhesive film between an air-permeable decorative skin and a fiber- reinforced thermoplastic resin layer, heating, pressing and molding the whole and setting air gaps at a specific ratio to the resin layer. CONSTITUTION:When a laminated molding 7 is molded, a sheet-shaped molding blank 1 is heated in a far infrared ray heating furnace 2 first. A hot melt type adhesive film 8 is interposed between a sheet-shaped molding blank 4 heated and an air-permeable decorative skin 5, and inserted into a molding die 6. The whole is pressed and molded under conditions, in which an aimed expansion coefficient is acquired, while both the blank 4 the skin 5 are unified, thus completing a porous laminated molding 7. The sheet-shaped molding blank 4 heated at that time is expanded by heating, and the exposure of reinforcing fibers is increased. The sheet-shaped molding blank 1 is formed of a thermoplastic resin layer containing not less than 10vol.% reinforcing fibers while 5-75vol.% air gaps are set to the thermoplastic resin layer. |
