(Comparative Example 2) In Comparative Example 2, an adhesive agent made of an epoxy resin was used, which was applied to the joint surface in the same manner as in Example 3 and treated at a temperature of 80 ° C to obtain a composite material. The pieces were joined together and the obtained pieces were evaluated in the same manner as in Example 1. As a result, although the bonding strength was developed, Comparative Example 1
Like the above, the fracture occurred at the joint surface and was 50 MPa, which was much lower than that in Example 3. Also, due to the difference in thermal expansion with heating, 1
It peeled off at the joint surface at a temperature of 50 ° C.

As described above, according to the joining method of the present invention, sink marks are not generated in the joined composite material,
Further, it has become possible to provide a joining method in which peeling does not occur on the joint surface even when heated, and further, the joint can be performed firmly without processing the joint surface. Thus, according to the present invention, it is possible to perform bonding that is far superior to conventional ones, provided that the composite materials are made of aluminum or aluminum alloy.
