BONDED COMPOSITE OF THERMOPLASTIC-RESIN-BASED FIBER-REINFORCED COMPOSITE MATERIAL AND METAL MEMBER, AND METHOD FOR PRODUCING BONDED COMPOSITE

摘要

A composite including: (I) a fiber-reinforced composite material; and (II) a metal member joined and fixed to the fiber-reinforced composite material by welding. The fiber-reinforced composite material is composed of reinforcing fibers and a resin composition. The resin composition contains (A) a polypropylene-based resin and (B) a modified polyolefin-based resin. The polypropylene-based resin has a tensile modulus of not less than 1 GPa. The modified polyolefin-based resin is a modified polyolefin resin modified with at least one kind of monomer which is selected from carboxylic acid group-containing vinyl monomers and epoxy group-containing vinyl monomers. A weight ratio between (A) and (B) in the resin composition is 90:10 to 40:60.
