Effects of fiber reinforcement pattern on high frequency induction heating behavior of unidirectional and woven CFRTP laminates

Abstract

This study aims to reveal the induction heating behavior of CFRTP composites by high-frequency induction heating method. The material used is unidirectional CF/PPS (UD-CF/PPS) and satin weave CF/PPS (woven-CF/PPS) laminates. The effects of geometry of induction coils, coil height, heating time and the carbon fiber reinforcement of CFRTP laminates on heating behavior of CFRTP composites in induction heating were investigated. The experimental results revealed that the surface temperature of UD-CF/PPS and woven-CF/PPS laminates was increased with increasing the heating time. Moreover, the surface temperature was increased with decreasing remarkably the coil distance. It was also confirmed that the carbon fiber reinforcement of CFRTP laminates has an effect on induction heating behavior.
