Fraunhofer-Application Center Textile Fiber Ceramics TFK is working on the development of cost-effective processes suitable for series production with which inorganic, in particular ceramic fibres can be processed into 2D and 3D structures suitable for load. As preforms in CMC components, these structures can be used for new lightweight construction applications, for example in the aerospace, thermal engineering and automotive industries.
Typical materials are silicon carbide, mullite, basalt, carbon or glass fibres. Tailor-made structures for targeted weight savings are implemented and resource-saving and efficiency-enhancing solutions are made possible. Textile-reinforced CMC components are suitable for high operating temperatures and have a high damage tolerance, improved fracture toughness and impact load capacity, corrosion, wear and thermal shock resistance and thus a longer service life compared to monolithic ceramics.
