Developing Intrinsically Heatable SiC Tools

Abstract: The aim of the project was to develop a variothermal tool technology using innovative SiC ceramics in order to optimize the production of thermoplastic fiber composites. The development focused on a new, innovative tool design, the production of the ceramics with integrated cooling channels and intrinsic heating by means of ceramic heating elements, as well as the use of the tools for processing fiber composites. By the end of the project, it should be possible to produce thermoplastically reinforced fiber composite components that cannot be manufactured more cost-effectively using any other process because of their complex structure and geometry.
