Abstract
The manufacturing method includes surface treatment and bonding. In the surface treatment, micro-order or nano-order asperities are formed on a surface of the metallic member. The bonding includes directly bonding the metallic member and the fiber-reinforced resin member by repeatedly bonding a melted portion of the fiber-reinforced resin member to the surface of the metallic member while partially melting the fiber-reinforced resin member, the metallic member having the asperities formed by the surface treatment.

A method of manufacturing a composite member including a metallic member and a fiber-reinforced resin member bonded to each other, the method comprising:
- performing surface treatment in such a way as to form micro-order or nano-order asperities on a surface of the metallic member;
- and
- directly bonding the metallic member and the fiber-reinforced resin member by repeatedly bonding a melted portion of the fiber-reinforced resin member to the surface of the metallic member while partially melting the fiber-reinforced resin member, the metallic member having the asperities formed by the surface treatment.
A composite member comprising:
- a metallic member having micro-order or nano-order asperities on a surface of the metallic member;
- and
- a fiber-reinforced resin member in direct contact with the surface of the metallic member having the asperities,
- wherein after a temperature change impact test is conducted, a shearing strength in the composite member is reduced only by 15.4% or less as compared with a shearing strength before the temperature change impact test is conducted, the temperature change impact test repeating a cycle 300 times, the cycle including heating the composite member from 40° C. to 140° C., keeping the composite member at 140° C. for 30 minutes, cooling the composite member from 140° C. to -40° C., and keeping the composite member at -40° C. for 30 minutes.
