Document Type and Number:
WIPO Patent Application WO/2017/212835
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a reinforced base material, composite material component, and method for manufacturing the same with which formability can be improved while suppressing manufacturing costs even with a composite material component having a complex curved surfaces. The present invention is a method for manufacturing a reinforced base material (6) that can be used in a composite material component made from a fiber reinforced composite material, wherein: the outline of the composite material component is formed into a target shape; a continuous loop (3) is created with first reinforcing fiber yarn (2), and continuous loops (3) are joined together to form a knitted layer having a curved surface following the target shape; and a reinforced part is formed by passing a second reinforcing fiber yarn (4) through the continuous loop (3) and combining with the knitted layer.
