Applications of Fibre Reinforced C/C-SiC Ceramics

Abstract

Originally, the demands in space technology played the decisive role in the development of ceramic matrix composite (CMC) materials. High mass-specific characteristics and extreme temperature resistance are important selection criteria for materials used in jet engines and thermal protection systems of new space-craft and rockets. Within the last few years, the properties and the manufacturing methods of CMC materials were consistently improved, so that now also the industry in general can share in the profits of this new class of materials. The liquid silicon infiltration (LSI) process is regarded as the most promising process for industrial products, especially if the aspect of costs is considered. A summary of the potential applications of the resulting C/C-SiC ceramics produced with the LSI process is given in the following.
