It is known to use a molded product obtained by heating and pressurizing MC (sheet molding compound) for an interior part such as a ceiling material of an automobile. However, in recent years, automobile interior parts have been required to have higher rigidity and lighter weight, so that there has been a problem that the conventional SMC has reduced rigidity when the weight is reduced. As a solution to this problem, there has been proposed a molded product obtained by heating and pressing a phenol resin laminate in which glass fiber mats impregnated with a phenol resin are laminated on both sides of a paper core material.
However, the interior parts of the automobile must be molded into a curved shape along the inner surface of the body of the automobile, and there is a problem that the above-mentioned molded product cannot be formed into the curved surface required.
