摘要:
A method for molding a laminated body includes laminating a reinforced fiber base material on a molding surface of a molding jig to form a laminated body; attaching a pulling jig to a third lamination portion of the laminated body; forming a protrusive curvature part and a recessed curvature part in the laminated body by curving the laminated body along a protrusive curvature surface and a recessed curvature surface formed on the molding surface while pulling the end of the laminated body with the pulling jig; and densifying the laminated body by heating the curved laminated body while pressurizing the same. The reinforced fiber base material is laminated so that at least a part of a gap between layers of the reinforced fiber base material becomes a non-adhered state in a portion from the protrusive curvature part to the third lamination portion formed in the laminated body.
