To provide an aluminum and resin composite article which not only shows an extremely high adhesion strength and airtightness between an aluminum alloy-made aluminum shaped body and a resin molded article both being integrally joined to each other, keeps the excellent adhesion strength and airtightness of the aluminum-resin joined surface under the severe environment concerning temperature, humidity, dust, corrosive substance and the like, and shows excellence in corrosion resistance, durability and thermal resistance, but also can exhibit excellent performance in weatherability and tensile strength of the joined surface of the aluminum and resin, and to provide a method for manufacturing the same.
The aluminum and resin composite article contains the aluminum shaped body having an uneven part on the surface, and the resin molded body whose resin is butt-bonded to the aluminum shaped body. On the surface of the aluminum shaped body, an aluminum film is formed on the outermost surface of the uneven part, and a plurality of recessed parts resulting from the uneven part are formed. The resin penetrates the recessed parts of the resin molded body to make solidified fitting-in parts. The aluminum and resin composite article showing the excellent weatherability is constructed by the mutual engagement by the recessed parts and the fitting-in parts.
