Further, the molding is to cure the synthetic resin or the synthetic resin precursor impregnated in the soft foamed polyurethane sheet or the cork layer together with molding, but as a curing means, a curing agent,
Water, water vapor, heat, light or electromagnetic waves, or a combination thereof. More specifically, for example, a means for hot pressing a soft polyurethane foam sheet impregnated with the synthetic resin or the synthetic resin precursor, the soft foam polyurethane sheet after adding a curing agent to the synthetic resin or the synthetic resin precursor. Impregnated in and cold-pressed at room temperature, or hot-pressed to heat-cure, soft foamed polyurethane sheet impregnated with the above synthetic resin is contacted with a curing agent, water, steam, etc. and cold-pressed at room temperature. Or a means for hot-setting by hot pressing, a means for irradiating light, an electromagnetic wave or the like on the soft foamed polyurethane sheet impregnated with the synthetic resin or the like and cold pressing or hot pressing.

用を行なう。The flexible foamed polyurethane sheet can be molded because the shapeability is imparted by impregnating a curable substance such as a synthetic resin or a synthetic resin precursor. However, the soft foamed polyurethane sheet alone lacks rigidity and is inferior in molding shape stability. The cork layer is lightweight but has rigidity. Therefore, the flexible foamed polyurethane sheet is reinforced by attaching the cork layer to one side or both sides, and the molding shape stability is greatly improved. Further, since the cork layer contains air, the cork layer acts as a sound absorber together with the soft polyurethane foam sheet.

Let The above-mentioned cork layer is polymerized on one side of the above soft polyurethane foam sheet, and the pressure is 3 kg / by cold press at room temperature while irradiating ultraviolet rays.
It is formed into a car ceiling shape in cm 2 for 5 minutes. The photo-curable acrylic oligomer impregnated in the soft polyurethane foam sheet and the cork layer is cured during press molding by the ultraviolet irradiation, and similarly exudes from the soft polyurethane polyurethane sheet and cork layer by pressing pressure. And glue them together. After molding, a non-woven fabric as a covering material is attached to the surface of the soft polyurethane foam sheet via a hot melt sheet to obtain a molded ceiling (11) for an automobile as shown in FIG.
