A joining technology is necessary for the manufacturing process of CFRTP composite structures. This study aims to reveal the induction welding behavior of CFRTP composites by high-frequency induction heating method. The material used is woven-CF/PPS laminate. The double D type coil was used was for induction heating. The effects of coil moving speed, high-frequency power on the heating behavior of CFRTP composites and the influence in induction heating were investigated. The experimental results revealed that the surface temperature of woven-CF/PPS laminates was increased with increasing the high-frequency power and decreased as the coil moving speed increased. Moreover, the surface treatment could be suppressed with the cooling method. The coil was used calling double D type coil. The effects of high-frequency power and coil moving speed, and cooling method were investigated, the optimum condition was obtained to improve. The results of single lap tensile test, the strength was obtained at 42MPa when the high-frequency power was 475-550W.
