Automatization and robust manufacturing processes for composite aerospace structures are getting into the focus. Thermoplastic composites could be a good opportunity for robust and automated processes. Additive manufacturing technologies like the thermoplastic tape placement combined with welding technologies gives the possibility in manufacturing complex, highly integrated parts for cost efficient structures. By reducing single manufacturing steps the part costs could be reduced significantly compared to thermoset technologies. Highly automated processes allow a significant data evaluation of process parameters. These data could be evaluated in-situ. Defects could be recognized during the process. A entire NDT process afterwards isn’t necessary any more. The welding technology could replace the riveting technology that is appropriate for the composite material. A deep understanding concerning the cooling and melting behavior of the thermoplastic materials (PPS, PEEK, PAEK) are necessary for sufficient laminate quality regarding performance and tolerances. Therefore investigation on material level is supporting the process and technological development.
