Conventional methods for manufacturing a composite structure in which a fiber-reinforced plastic member and a metal sheet are bonded have potential for improvement with regard to manufacturing cost and bond strength between the fiber-reinforced plastic member and the metal sheet. The method for manufacturing a composite structure provided has the following steps: (a) preparing a metal sheet having a through-hole penetrating in the sheet thickness direction, a prepreg for constituting a fiber-reinforced plastic sheet, a mold having a pair of dies for obtaining a composite structure having a predetermined shape, the mold being capable of forming, at a position facing an open part on one side of the through-hole, a recess having a larger diameter than the open part on one side of the through-hole, and at least one patch member set in a position opposite the through-hole; (b) placing the prepreg and the metal sheet between the pair of dies; (c) closing the pair of dies together, and while the dies are closed, (ca) the prepreg and the metal sheet being molded in the predetermined shape while the prepreg and the metal sheet are in surface contact with each other, (cb) the prepreg and/or the patch member being pushed into the through-hole, and a shaft part integrated with the prepreg being formed, and (cc) a head part configured from at least the patch part, integrated with the shaft part, and engaged with the metal sheet being formed in the recess. |
