METHOD FOR MANUFACTURING JOINT MEMBER, AND JOINT MEMBER

摘要

Provided is 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 strongly joined. 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 including: 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 thereby combine the metal and the composite material into one.
