PURPOSE:To obtain a high quality FRP formed part with no sink on the surface of a product and at the same time contrive to reduce the consumption of energy necessary for forming by a structure wherein low melting point thermoplastic resin film, in which hardening agent is scatteringly sealed, is laminated to compound. CONSTITUTION:Pressure forming plastic sheet stock 1 consists in laminating film 4 sealed with hardening agent 3 therein to compound mainly being composed of resin, which reacts by contacting with the hardening agent. Because the low melting point thermoplastic resin film, in which hardening agent is scatteringly sealed and which breaks when pressure is loaded thereon, the plastic sheet stock can be pressure-formed at normal temperature, resulting in suppressing the thermal contraction of plastic, which may occur having the cooling of a formed part, and enabling to obtain a high quality FRP formed part with no sink developed and at the same time enabling to contrive to reduce the consumption of energy necessary for forming the part. |
