Abstract
Research project CerMeTex - objectives: research focus was put on the development of technologies for production of textile metal fibre ormetal filament semi-finished products and in generating chemical compounds between metal-based textile reinforcement structure and ceramic matrix in composites. As part of the work 6 different ceramic manufacturing technologies were examined by using selected ceramic raw materials (ZrO2 und Al2O3) in combination with textile semi-finished metal products. Different textile technologies like nonwovens production, weaving, knitting and embroidery were used to develop these semifinished products. Characterizations of metallic raw materials as well as semi-finished products were also subject of investigations. Experimental: during project work nonwoven structures of metal long fibres and metal short fibres were investigated. The developed nonwovens could be embedded Into ceramic matrix by using slip casting, freeze foaming and injection moulding. Combinations of ceramic and metal fibre material could especially be found using injection moulding when the nonwovens contributes to increase component strength not only by form-fitting, but also by chemical bonding in the boundary layer of ceramic and fibre. Sandwich structures as well as one-sided injection moulded components were prepared during this process. One-sided injection moulded composites with the metallic side partially exposed enable the production of innovative composites between ceramics and low-melting metals and offer completely new constructive approaches. Results: the institutes IKTS and STFI have developed new metal fibre-ceramic composites and components. These materials have improved damage tolerance and special functionalities that partly rise from divergent properties of metallic and ceramic composite partners.
