Abstract

Recently, the automobile industry is under increasing environmental regulation and must improve fuel efficiency by making cars lighter. In order to minimize weight, carbon fiber reinforced plastics (CFRP) materials with excellent mechanical properties are gaining attention, and various technologies are being developed for joining multiple materials as the application of composite materials increases. In this study, self-piercing rivets (SPRs) were used to assess the quality of the joining between CFRP and metal materials. A series of experiments was conducted to select the shape of the rivets and dies according to the materials, and the type of failure of SPRs was analyzed. The quality of the joining was evaluated using the gap between the rivet head and the upper plate, remaining thickness of the lower plate, the amount of interlock between the rivet and lower plate, and the shear strength evaluation and fracture modes were analyzed.

Keywords:

Self-piercing riveting, Carbon fiber reinforced plastics (CFRP), Multi material integration, Shear strength, Fracture mode
