METHOD FOR NON-PENETRATION JOINING OF MEMBERS, AND NON-PENETRATION JOINING STRUCTURE

WIPO Patent Application WO/2018/003175

A1

[Problem] To provide a method for non-penetration joining of members and a non-penetration joining structure, whereby a joining member and a member to be joined are joined with high airtightness. [Solution] A joining member 4 is retained by a receiving mold 6 so that a protruding part 4c of the joining member 4 is exposed, a joined member 5 is placed over the joining member 4 so that the protruding part 4c of the joining member 4 is positioned in a bag hole 5a of the joined member 5, the joined member 5 is compressed against the receiving mold 6, whereby the joined member 5 and the joining member 4 are plastically deformed at the same time, excess thickness of the joined member 5 is wrapped around and into an undercut part 4cc while the undercut part 4cc is formed on the joining member 4, and both members are non-detachably joined together. Through this configuration, not only can molding of the joined member 5 and joining with the joining member 4 be performed simultaneously, but a groove for preventing the excess thickness of the joined member 5 from coming unwrapped can be formed by the undercut part 4cc. A composite component can also be manufactured in which the joining member 4 and the joined member 5 are joined in a state of non-penetration, i.e., a state in which airtightness is maintained at a joined portion.
