A simulation model for the induction heating of UD tape-based thermoplastic composites is presented in this work. The model is based on the electrical ply properties which were determined experimentally for two commercially available carbon reinforced tape materials. Moreover, the interrelation between the measured electrical conductivities and the fiber distribution in the tape and laminates is discussed based on microscopic structure evaluation. The model was validated experimentally for the induction heating of cross-ply laminates. Subsequently, the effect of the experimental variability in the measured conductivities on the heating behavior was investigated using the simulation model. It was found that the material variability can have a significant effect on the heating behavior.

在这项工作中提出了一种基于 UD 带的热塑性复合材料的感应加热仿真模型。该模型基于对两种市售碳增强胶带材料通过实验确定的电气层特性。此外，基于微观结构评估讨论了测量的电导率与胶带和层压板中的纤维分布之间的相互关系。该模型已通过实验验证用于交叉层层压板的感应加热。随后，使用模拟模型研究了测量电导率的实验变异性对加热行为的影响。发现材料可变性对加热行为具有显着影响。
