Abstract
A manufacturing method of a composite structure includes: (a) preparing: a metallic sheet(s) having a through-hole(s) penetrating throughout the metallic sheet(s) in its thickness direction; (b) setting a prepreg(s), constituting a fiber reinforced plastic sheet(s), and the metallic sheet in a pair of dies, which have a recess(es) arranged at a position(s) opposed to one side opening(s) of the through-hole(s), the recess(es) having a larger diameter than the one side opening; (c) closing the dies, wherein, upon closing, (ca) the prepreg(s) and the metallic sheet are molded to the predetermined shape, while surface-contacting therebetween, (cb) at least one of the prepreg(s) and a patch member(s) is extruded into the through-hole(s), so that the shaft part is molded, and (cc) the patch member(s) forms at least part of a head part(s) in the recess(es), the head part(s) integrated with the shaft part(s) and engaging on the metallic sheet(s).
