| Outline of Final Research Achievements |
Dissimilar materials joining of plastic to metal was performed. Effects of mechanically- and chemically-structured interface on the joining properties in addition to joining conditions were investigated. Several surface treatments such as grinding, oxide treatment, laser scanning, blasting and chemical treatment were applied on the metal surface to form the structured interface.
Aluminum alloys and steels plates as metals, and polyamide (Nylon) and polyethylene plates as plastics were used as experimental materials. Based on the results of joining between metals/plastics, dissimilar joint formation between metals/ carbon fiber reinforced plastic (CFRP), which consisted of polyamide and carbon fiber, were carried out. The strong joints, which were fractured at the plastic and CFRP base plates by tensile shear test, were obtained at the suitable joining condition and structured interface.
