| Outline of Final Research Achievements |
The purpose of this study was to develop a metal-plastic joint that exhibits high joint strength and durability by a novel welding method using a functional interlayer and porous film, and to show the mechanism of the excellent joining properties. As a result, the conditions for the preparation of an effective functional interlayer and the formation of a porous film were clarified, and the joining conditions for achieving maximum joint strength were also clarified. Furthermore, the mechanism of the anchoring effect of the resin penetrating into the pores of the porous film was found to be strongly dependent on the depth of the pores rather than the size of the pores. Further investigations will lead to the realization of dissimilar material joints with high strength and durability.
