Ceramic composite brake discs made of carbon fibre reinforced silicon carbide (C/SiC, commonly known as carbon ceramic), manufactured by the liquid silicon infiltration (LSI) process, have become established in the sports car sector and in high-performance series production vehicles since their market launch in 2001. To date, however, it has above all been the high costs that have prevented an increase in production volumes and further dissemination into vehicle classes with more attractive unit numbers. In order to support the efforts towards cost reduction, a material and design concept suitable for economical series production was developed in this work. On the basis of a defined reference variant, alternative material and design concepts for the brake disc ring, the brake disc pot and the joining technology were developed, examined with regard to their manufacturability and properties, and comparatively assessed against one another. For this purpose, all individual steps of the manufacturing process, from the fibre through to the ready-to-install brake disc, were considered. Based on the results of the material and component analyses, an overall concept improved in functional, production-specific and economic respects could finally be presented.
