Abstract: This paper studied the temperature history and distributions at key positions during induction welding of thermoplastic composites. Carbon fiber reinforced poly(phenylene sulfide) (CF/PPS) coupons were fabricated, with in-situ thermocouple monitoring. Effects of welding parameters on surface morphology were explored, along with fundamental influences from air cooling and sustaining press. We further evaluated single-lap-shear strength and compared with data from hot pressing. Finally, some approaches were suggested for processing improvements.
