<P>PROBLEM TO BE SOLVED: To provide a joining method of fiber-reinforced thermoplastic resin composite materials wherein a mechanical strength of the joint is not lowered. <P>SOLUTION: When joining parts of a fiber-reinforced thermoplastic resin composite material A and a fiber-reinforced thermoplastic resin composite material B are joined by welding, one or more protrusions are formed on the joining part of the composite material A in advance while the joining part of the composite material B being pre-heated and softened in which the protrusions of the composite material A are pushed into. Thereafter the joining parts of the composite material A and composite material B are fused by heat and combined. <P>COPYRIGHT: (C)2008,JPO&INPIT |
