Abstract: PROBLEM TO BE SOLVED: To realize a molding under a pressure smaller than a specified value by a method wherein a lightweight molding part is molded out of a molding composition including a thixotropic substance such as a fumed silica and an arbitrary filler. SOLUTION: In order to manufacture this molding part, an saturated thermosetting resin, a shrinkage controlling additive, a thixotropic substance such as a fumed silica, a free radical initiator, an alkaline earth oxide or hydroxide thickner and a monomer are mixed together, A sheet is formed at 85-170 deg.C under the pressure of 3.5 MPa or less so as to generate a resin and a glass uniform flow outside the edge part or a part. As the thixotropic substance useful for a composition to be used, a hydrophilic fumed silica, a hydrophobic fumed silica, polyamide fibers, a bentonite clay, polyolefin fibers, a carbon black, polyester fibers or a wollastonite is exemplified. The desirable thixotropic substance to be used in the process is the fumed silica.
