Abstract: The induction welding of aerospace qualified polyaryletherketone prepregs (PEEK and PEKK) were studied to screen the process control parameters for the welds with sufficient quality using KVE’s leading thermoplastic induction welding technology. The microscopic analysis of weld lines and single lap shear testing results demonstrate satisfactory joining strengths of welded assemblies under appropriate welding conditions. Utilization of a lower melting PAEK film on the surface of the PEKK adherents could be able to produce satisfactory welds at significantly lower welding temperatures. Factors such as crystallinity/crystallization kinetics and melting points are discussed relative to achieving a robust process for induction welding.
