PROBLEM TO BE SOLVED: To provide a method for producing an unsaturated polyester resin molded article having excellent productivity, a favorable working environment, and a uniform foam layer laminated thereon. SOLUTION: Unsaturated polyester resin, inorganic filler, After preparing the SMC molding material from the reinforcing fiber, putting it into a mold and heating and compressing it, the mold is opened to provide a certain gap between the cured body and the mold, and polyurethane foam is formed in this gap. The undiluted solution is discharged and foam-hardened to obtain an unsaturated polyester resin molded product on which a foam is laminated. |
