| Outline of Final Research Achievements |
This study aims to investigate the fusion bonding interface phenomenon between carbon fiber reinforced thermoplastics (CFRTP) and dissimilar materials such as carbon fiber reinforced thermosetting plastics (CFRP).
In order to improve quality of the fusion bonding interface, spread carbon fibers or woven carbon fiber was used as joining layer, and fusion bonding was performed by resistance heating or ultrasonic heating. From the experimental results, it was clarified how to avoid the current leakage to joining target during resistance welding. It was also suggested that the application of micro-sized thermoplastic powder or thermoplastic epoxy polymer to improve the tensile shear strength of the joining part between CFRTP and CFRTP.
