Method and apparatus for molding thermosetting composite material

摘要

The invention provides a means for molding a prepreg material with a curved surface formed by impregnating carbon fiber or glass fiber with thermosetting resin. A prepreg sheet 100 is shaped into an L-shape, and an L-shape preformed channel member 120 is molded via a hot press unit 210 and a cold press unit 220. The curing rate of the perform is 30 to 60 %. The preform 120 is molded into a curved member having a radius of curvature R1 in a secondary molding apparatus 300, which is then cut to form channel members 30. The curing rate thereof is 60 to 80 %. Then, these channel members 30 used as reinforcements of a plate member are completely cured in an autoclave to form the molded product.
