摘要： In this joint structure which has a reinforcement part that is formed by bonding a composite material and a reinforcement material via an adhesive, the composite material comprises a plate part formed by laminating multiple textile sheets and a raised part formed by further laminating a textile sheet on the plate part, the plate part and the raised part both have the respective surfaces covered by a single textile sheet, the reinforcement part comprises the raised part and the reinforcement material that is bonded to the raised part via the adhesive, and a first boundary between the plate part and the raised part and a second boundary between the raised part and the reinforcement material are disposed at positions different from each other in the in-plane direction of the lamination interface of the laminated textile sheets.

摘要： The present invention enables easy achievement of a desired shape and inhibits reduction in strength. This method for producing a composite material (10) comprises: an insertion step (S10) for inserting inner members (12) each obtained by impregnating a second reinforced fiber with a resin, into spaces (35) in an outer member (14a) that is formed from a first reinforced fiber having been woven and extending corrugatedly, and that has openings (36) at at least one end portion thereof such that the spaces (35) formed thereinside is connected to the openings (36); and a composite material forming step for curing the resin of the inner members (12) so as to bond the outer member (14) and the inner members (12) together, and thereby forming the composite material (10) in which the outer member (14) and the inner members (12) are bonded together.
