Thermoplastic fiber composites enable the manufacturing of integral hybrid structures in large-scale processes. These structures combine lightweight construction and functional integration. While such approaches are already being used in series applications in the automotive sector, in the aviation sector thermoplastic applications are mainly monolithic. However, the significant potential of thermoplastic structures with integrated functions can be exploited in this sector, too. Such integrated production approaches are increasingly relevant, especially in view of increasing quantities at high cost pressure. In aviation, specific material systems are needed which not only meet the mechanical requirements but also function at high operating temperatures and have very good flame retardant properties. Together with its partners Airbus Operation GmbH, Laser Zentrum Hannover e. V. and TenCate Advanced Composites B. v., the Fraunhofer Institute for Chemical Technology ICT has developed a hybrid reinforcing component - based on the high-performance thermoplastic polyetherimide (PEI) - for the aviation sector. This component combines the advantages of the material, process and design. These advantages are fully exploited in a demonstrator developed for potential appl ication in the cargo compartment of airplanes.
