  • Abstract:Being contactless and volumetric, Induction heating has proven to be an effective method for producing high strength weld joints between Carbon Fiber Reinforced Thermoplastic (CFRT) components. There are inherent challenges with the implementation of this technology due to the anisotropic nature of CFRT. The anisotropic electrical and thermal properties of CFRT plate are described. The properties are inputted to a FEA program for electromagnetic and thermal simulation. The program is used to design an induction coil with a goal of achieving uniform temperature distribution in a lap joint between two CFRT plates. Effect of frequency, material orientation, and coil design is examined.
