Ceramic matrix composites (CMC) overcome the disadvantages of conventional ceramics, exhibiting superior damage tolerance, fracture toughness, strain to failure and thermal shock resistance. The market for CMC is rapidly growing from 8.8 billion USD in 2021 to 25 billion USD in 2031 (per Allied Market research). The applications for these materials can be found in aircraft engines, e.g. rocket nozzles, gas turbine components and in brake components, nuclear reactors and wear resistant components.
The main drawback of these materials are the high costs due to the raw materials and the high temperature processing. Aspects of sustainability and recycling are underestimated as well, particularly because of the high scrap rates related to inadequate process control. Therefore, the motivation is high to initiate research collaborations to overcome these challenges.
Within the proposed project, different approaches are addressed and studied, in order to develop more sustainable materials on the basis of C/C, C/SiC, SiC/SiC and OFC (oxide fiber composites).
