MAX phase ceramics show great potential for a new, innovative generation of engineering materials for energy technology due to their excellent mechanical properties in a high-temperature atmosphere. Fibre-reinforcement of MAX phases show great potential to further increase the materials engineering capabilities. However, the mechanisms to introduce continuous fibre-reinforcement into the novel ceramic system are not understood yet. Suitable processes for the production of continuous fibre-reinforced ceramics are currently formulated only by colloidal manufacturing processes. A major challenge of colloidal processes regards the homogeneous impregnation of textile reinforcement structures. However, the formulation of highly filled, fibre-reinforced green bodies decreases with increasing complexity of the molded part design. For this purpose, the production of Al2O3(f)-Ti2AlC-CMC is investigated both for the wet-winding and the pressure slip casting technology. Through interdisciplinary collaboration between textile mechanical engineers and ceramicists, the ContiMAX research team is pooling the necessary know-how to develop an innovative Ti2AlC composite, reinforced by multidirectional alumina textiles. To this end, the research will investigate basic mechanisms of MAX phase CMC processing to contribute to the development of future sustainable material systems to replace a large number of metallic high-temperature elements and wear-intensive components.
