Abstract
A method for providing an integrated composite article made of a metal and a resin is provided. A crystalline thermoplastic resin composition is provided as a resin material. A plate material of various kinds of Al alloys having a thickness of 0.5 to 1.5 mm and having been subjected to a chemical treatment of NMT and cut out to be of a form and a dimension is placed in a metallic mold for an injection molding and injecting the crystalline thermoplastic resin composition into the metallic mold to form the integrated composite article having a final plate shape including curved face portion. The integrated composite article is provided as a roof of an automobile, and contribute to promotion of lighter weight of a vehicle, reduction of CO2, coping with problems of global warming.
Claims3
