Document Type and Number:
WIPO Patent Application WO/2020/121648
Kind Code:

Abstract:
This method for molding a laminated body is provided with: a lamination step S1 of laminating a reinforcing fiber base material on a molding surface 21 of a molding jig 10 to form a laminated body 5; an attachment step S3 of attaching a pulling jig 13 to a third lamination portion of the laminated body 5; a deformation step S4 of forming a protrusive curvature part and a recessed curvature part in the laminated body 5 by curving the laminated body 5 along a protrusive curvature surface and a recessed curvature surface formed on the molding surface 21 while pulling the end of the laminated body 5 with the pulling jig 13; and a densification step S5 of densifying the laminated body 5 by heating the curved laminated body 5 while pressurizing the same. In the lamination step S1, the reinforced fiber base material is laminated so that at least a part of a gap between layers of the reinforcing 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 5.
