Abstract: High-strength fiber-reinforced thermoplastic composites are beginning to replace their traditional thermoset counterparts in the aerospace industry. Due to the electrically conductive nature of carbon fiber, induction welding can be leveraged to achieve valuable weight savings in certain subassemblies and structural joints by elimination of fasteners. In order to reduce trial and error while developing the induction welding process, a numerical model was employed to investigate the inductive heating on thermoplastic composite material. In this work, a CF/PEKK laminate and induction coils with and without a flux concentrator was considered. The simulated temperature data is then validated against experimental data that included cross-ply and quasi-isotropic stacking sequences. Critical factors that affect the heating rate and distribution were shown to be the laminate stacking sequence and the addition of the magnetic flux controller on the induction coil.
