Title:
ALUMINIUM/RESIN COMPOSITE EXHIBITING EXCELLENT WEATHER RESISTANCE AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2011/071102
Kind Code:
A1
Abstract:
Disclosed is an aluminium/resin composite which: exhibits extremely high interfacial adhesion strength and air tightness between an integrally-bonded, shaped aluminium article made from an aluminium alloy, and a molded resin article; retains the excellent adhesion strength and air tightness of the aluminium/resin bond surface in harsh environments such as those caused by temperature, humidity, dust, and corrosive materials; and is corrosion resistant, heat resistant, weather resistant, durable, and exhibits excellent peel strength on the aluminium/resin interfacial surface. Also disclosed is a manufacturing method for the aluminium/resin composite. The aluminium/resin composite contains a shaped aluminium article having undulations on the surface, and a molded resin article which is bonded to the shaped aluminium article when the resin is butted thereto. A plurality of concave sections are formed due to the undulations, and an aluminium coating film is formed on the outermost surface of the undulations. Fitting sections are formed on the molded resin article where the resin enters the concave sections and hardens. The components of the aluminium/resin composite which exhibits excellent weather resistance are engaged by the concave sections and the fitting sections.
