PURPOSE:To obtain the laminated molded item concerned having the surface hardness, weatherability and external appearance, which are equal or superior to those conventionally obtained by painting, by a method wherein a process for arranging thermosetting resin sheet under uncured or semi-cured state on the inner surface side of an mold by vacuum forming and/or air pressure forming, is provided. CONSTITUTION:Thermosetting resin sheet under uncured or semi-cured state, which is mainly made, for example, of reactive acrylic resin having the weight-average molecular weight of 50,000-1,000,000 and blocked isocyanate and cut to the predetermined dimensions, is arranged inside a mold so as to be brought into close contact with a mold surface under ordinary temperature or heat by vacuum forming and/or compressed air pressure forming. Next, by being introduced in the mold, fiber reinforced thermoplastic resin sheet is placed on inside the thermosetting resin sheet. The fiber reinforced thermoplastic resin sheet is introduced in the mold after being heated up to its deformable temperature. Next, after the closing of the mold, the thermosetting resin sheet and the thermoplastic sheet are pressmolded. After that, a molded item is heated (with infrared rays, hot air or the like), so as to thoroughly set the thermosetting resin sheet. |
