| Outline of Final Research Achievements |
Dissimilar material joining of plastic and metal is a critical issue in weight saving of transportation in low carbon society. In this research, we will challenge research subjects such as "Is there really a third bonding method other than adhesives and mechanical fastening? ". We developed the joining method that plastic and metal could be directly laser bonded without using inclusions such as adhesives. Therefore, we conducted a laser direct joining of metal to the thermoplastic engineering plastics which are demanded in the low carbon society, and investigated the bonded interface by an atomic level structural analysis and an electronic orbital calculation based on quantum mechanics. From the obtained results, we clarified "what is important for this dissimilar material joining mechanism?" and “whether this method can be used as the third joining method?”.
