| Outline of Final Research Achievements |
Metallic materials have excellent strength and toughness, and plastic materials have lightweight and excellent formability. Joining of both materials is carried out to achieve the reduction of the weight and high functionality. The products which are composed of both materials are used in a wide range of industrial fields. In this study, to solve several problems of the conventional joining method, joining of an acrylic sheet which was a kind of brittle plastic material and a lightweight aluminum alloy sheet by using an aluminum alloy rivet was attempted by the punching rivet method. As a result, the acrylic sheet and aluminum alloy sheet were joined without fracture of the acrylic sheet, and the dissimilar joint had high joint strength. There is a possibility that the punching rivet method becomes a new joining method for plastic materials and metallic materials.
