Development of separation technology for dissimilar material bonding products of steel plate and CFRTP using the eddy current method

Owing to their lightweight and high specific strength, carbon fiber reinforced plastics (CFRTPs) are now receiving widespread applications in the transportation and energy industries. In this regard, developing technology for separating and extracting CFRTP from dissimilar material bonding products of metal and CFRTP has become a research hotspot. Therefore, in this study, we developed a separation technology for dissimilar material bonding products of steel sheet and CFRTP using the eddy current method. As a result, we succeeded in separating dissimilar materials using a fabricated induction heating system. In addition, atomic force microscope (AFM) analysis of CFRTP was conducted to confirm the change in physical properties before and after heating.
