Pre-ceramic polymers were used as organic vehicle in this study forming a ceramic matrix after pyrolysis. Carbon short-fibres were chosen as fibre materials. Because of inadequate processing properties of the used pre-ceramic polymer, blending with thermoplastic waxes and process additives was necessary. An amorphous Si–C–N network was obtained as the matrix of the short-fibre composite … Read more

Since October 2020, the Working Group Shaping and Additive Manufacturing has been working in new and larger laboratories and can proudly present all devices for AM under one roof. At approx 200 … Read more
Oxide ceramic fibres are required for reinforcement of metal matrix and ceramic matrix composites – especially in high temperature applications. Fraunhofer Center HTL/DE has been successfully developing customised oxide and non-oxide ceramic fibres for more than 20 years. In the field of oxide fibres, R&D work is focused on reinforcing fibres in the mullitecorundum system.
As part of the production changeover from the former manufacture of electrical porcelain and other silicate ceramics to the production of products made of high-purity oxide ceramics and ceramic filtration membranes, the composition of the wastewater stream changed significantly. As a result, the original wastewater treatment technology could no longer guarantee the required quality criteria. … Read more
Textiles are no longer available just in their customary forms, but also with special functional properties and in combination with various other materials. This opens up a broad range of opportunities for quantum leaps in completely new products. Such technical textiles are primarily used in the automotive industry, aerospace, road construction, garden and landscaping, sports … Read more
