Abstract
The surface of an aluminum alloy shaped product is covered with ultrafine recesses by being dipped in an eroding aqueous solution, or has formed thereon a metal oxide layer covered with the openings of ultrafine pores by anodizing. On the resin side, there is prepared a polyamide resin compounded with an impact resistance modifier, a mixture of an aliphatic polyamide and an aromatic polyamide, or a mixture of aromatic polyamides. The aluminum alloy shaped product is inserted into an injection mold, and a polyamide-type resin composition is injected onto the surface of the aluminum alloy shaped product, to manufacture an integrated composite.
