The creep properties of powder metallurgy (PM) discontinuous SiC-Al alloys (whisker and particulate) and their Al matrices have been the subject of many studies recently that have aimed not only at assessing the potential of the PM SiC-Al alloys for use as high temperature materials but also at identifying the origin creep strengthening in such materials. As a result of these studies, several sets of experimental results are now available. This paper reviews some of the results. Emphasis is placed on the identification of issues related to early work and on efforts made recently to clarify them. In addition, recent developments regarding the roles played by SiC particulates and the Al alloy matrix during the creep of a PM SiC-Al composite are discussed

Ceramic Matrix Composites based on reinforcements of carbon fibers and matrices of SiC show superior tribological properties. In combination with their low density, high thermal shock resistance and good abrasive resistance, these Si-infiltrated C/C materials are promising candidates for advanced fr
sensitivity, the legibility and the reliability will be addressed. Examples will be chosen among fibre-reinforced ceramic, polymer or metal matrix composites
