Patent ID: 7959838

Claim:
A method for producing a fiber-reinforced composite material molding comprising: (1) preliminarily adjusting a temperature of a mold to be equal to or more than the curing temperature of a thermosetting resin; (2) preparing a molding material wherein (A) a substantially continuous reinforced fiber is impregnated with the thermosetting resin, and a volume of the molding material is more than 100% and equal to or less than 120% of a volume of a finished molding, and a thickness of the molding material is more than 100% and equal to and less than 150% of a thickness of a finished molding; (3) putting the molding material in the temperature-adjusted mold which has one side surface area S 2 , wherein the molding material has one side surface area S 1 and S 1 /S 2 is 0.8 to 1; (4) fastening the mold following (3) and such that the whole inside of the mold is filled with the molding material; and (5) compression molding to obtain a finished molding, wherein the prepared molding material additionally comprises (B) a material impregnated with a thermosetting resin in a staple reinforced fiber wherein component (B) is laminated on at least one surface of component (A).
