る。2. Description of the Related Art Conventionally, for example, when manufacturing a door inner panel for a vehicle, a thermoplastic elastomer (TPE) or polyvinyl chloride (PVC) or the like is integrally laminated with a foam layer as a surface material. When a molded product is used and a resin plate material such as polypropylene (PP) is used as the base material, an adhesive is applied and dried on the base material surface after the primer is applied, and the adhesive is applied to the base material. The foaming foam layer is placed in contact with the base material, and the facing material is laminated on the base material, and then adhered and fixed by vacuum forming. Also, when a wooden board is used as the base material, the adhesive is applied to the surface of the base material to be dried and adhered, and then the covering material is adhered and fixed to the base material by vacuum forming as described above. .

２に強固に接合することができる。Before the foamed resin layer 1c 'is cured, as shown in FIG. 5a, the facing material 1 is placed on the base material 2 assembled in the lower mold W 1 for vacuum or pressure forming, As shown in FIG. 5b, the cover material 1 is press-molded at room temperature so as to be compressed by the upper mold W 2 . Depending on this press molding, the uncured foam material of the foamed resin layer 1c 'is removed through the through hole 2 of the substrate 2.
a, 2b ... And when the wooden board is the base material 2, the foamed material of the foamed resin layer 1c 'enters between the fluffy wood fibers. Then, when the foamed resin layer 1c ′ is cured, it becomes a foam layer 1c ″ integrated with the foamed foam layer 1b as shown in FIG. 1, and the through holes 2a, 2b ... Since the foam material components 1d, 1d ... Of the foam layer 1c ″ that have entered enter the anchoring action, the facing material 1 can be firmly bonded to the base material 2 so that delamination or the like does not occur.

する必要もない。As described above, not only is it unnecessary to use an adhesive when bonding the facing material 1 to the base material 2, but rigidity can be imparted if the foamed foam layer 1c is formed of foamed polypropylene mixed with glass fibers. By using the base material 2 having a low basis weight, the weight of the molded product can be reduced.
Further, since the cover material 1 can be joined to the base material 2 which is preformed in a three-dimensional shape while being in the form of a sheet, it is not necessary to separately form it.
