Abstract
There is provided a method for manufacturing a joint member obtained by joining a carbon fiber composite material containing a thermoplastic resin as a matrix and a metal. The method includes a step (i) of forming an uneven shape having a depth of 0.02 to 0.6 mm on a surface of the metal at a joining portion; a step (ii) of providing a thermoplastic resin layer having a thickness in the range of 5μm or more and 5 mm or less at a joining portion between the surface of the metal and a surface of the composite material; and a step (iii) of melting the thermoplastic resin layer by heating the joining portion to thereby combine the metal and the composite material into one.

A method for manufacturing a joint member in which a carbon fiber composite material containing a thermoplastic resin as a matrix and a metal are joined, the method comprising:
- a step (i) of forming an uneven shape having a depth of 0.02 to 0.6 mm on a surface of the metal at a joining portion;
- a step (ii) of providing a thermoplastic resin layer having a thickness in the range of 5 μm or more and 5 mm or less at a joining portion between the surface of the metal and a surface of the composite material;
- and
- a step (iii) of melting the thermoplastic resin layer by heating the joining portion to combine the metal and the composite material into one.
A method for manufacturing a joint member obtained by joining a carbon fiber composite material containing a thermoplastic resin as a matrix and a metal, the method comprising:
- a step of forming plural pieces of an uneven portion having a depth of 0.02to 0.6 mm on a surface of the metal at a joining portion;
- a step of forming an organic coating layer of a triazine thiol derivative on the surface of the metal,
- a step of fusing a thermoplastic resin on the organic coating layer of the triazine thiol derivative on the surface of the metal to form a thermoplastic resin layer having a thickness in the range of 5 μm or more and 5 mm or less,
- a step of layering a thermoplastic carbon fiber composite material on the thermoplastic resin layer to thereby form a laminate including the metal/ the organic coating layer of the triazine thiol derivative/ the thermoplastic resin layer/ the thermoplastic carbon fiber composite material, and
- a step of melting the thermoplastic resin layer by heating the resulting laminate together with pressurization in a thickness direction to thereby combine the metal and the composite material into one.
