The German Institutes of Textile and Fiber Research Denkendorf (DITF), Denkendorf/Germany have been developing ceramic fiber composites, so-called CMCs (ceramic matrix composites), with special property profiles for decades.
Recently, considerable investments have been made in plant technology, as the aim of the research activities is to transfer the manufacturing process to industrial production. The focus is on the development of oxide ceramic fibers based on mullite and corundum.
The decisive property of these fibers is their distinctive high temperature resistance. The so-called OXCEFI ceramic fibers developed at the DITF already achieve values that exceed those of the best commercially available fibers.
In this respect, interest in their economical implementation is also growing. Industry is already showing great interest in transferring the manufacturing technology into industrial production. Ceramic composites are used in high-temperature lightweight construction, where, for example, they can replace metallic super-alloys and outperform them in terms of temperature resistance, specific strengths and modules. One field of application is the development of new types of aircraft gas turbines and stationary gas turbines with reduced emission values and higher efficiencies.
