Aluminum alloy composite and method for joining thereof
The object of the present invention is to strongly join an aluminum alloy part with an frp prepreg. An object obtained by subjecting an aluminum alloy to a suitable liquid treatment so as to form a surface having large, micron-order irregularities and also fine irregularities with a period of several tens of nanometers, eliminating the presence of sodium ions from the surface and additionally forming a surface film of aluminum oxide, which is thicker than a natural oxide layer, has been found to have a powerful adhesive strength with epoxy-based adhesives.
