Thermoplastic composites offer new manufacturing processes over composites with thermoset matrix. Since the prepreg material can melt, be formed and solidify in a short amount of time, processes like automated tape placement with in-situ consolidation are viable. However, matrix materials like PEEK and PPS pose challenges due to their high process temperature and their semi-crystalline nature. Combined with the highly dynamic process the behaviour of the part during and after manufacturing is complex to predict and to simulate. At the DLR in Stuttgart a method for simulating plane and curved parts was developed. Using a moving boundary condition for the laser of the AFP-machine, the deformation and interlaminar shear stress can be predicted and the danger for process-induced damage like delamination estimated. This work will help to minimize tolerances and initial costs of parts and contributes to the development of a full digital twin for the entire manufacturing process.
