抄録

In carbon fiber reinforced thermoplastic matrix composites (CFRTPs), interface between carbon fiber and matrix resin play an important role on the performance of the composites. Because interfacial debonding easily takes place during processing or use due to bad adhesiveness of thermoplastics, detect and repair techniques of interfacial debonding are inevitable to utilize CFRTPs practically. In this study, direct heating of the fibers in a CF/PP composite by means of MHz high-frequency induction was applied to melt and re-weld debonding at the interface. Bending modulus increased with IH. and it was supported by SEM observation of fracture surface where gaps at fiber/matrix interface disappeared after IH. Temperature rise at specimen surface got faster in proportion to the bending modulus increase. It was considered to result from rewilding at the interface and so the temperature rise at the surface during IH can be adopted to detect interfacial debonding.
