Previous work presented at the 1995 Cocoa Beach conference by Ceramics Kingston Ceramiques Inc. (CKCI) and the National Research Council of Canada`s (NRC) Institute for Aerospace Research showed that net shape parts of molybdenum disilicide and MoSi{sub 2}-based composites could be prepared by a proprietary process involving self-propagating high-temperature synthesis (SHS). The process has recently been improved and used to prepare hot pressed MoSi{sub 2}-based composites containing 20 vol.% silicon carbide whiskers (which are produced by CKCI). The physical, microstructural and mechanical properties of this composite have been evaluated at room temperature and some mechanical testing has been performed at 1000{degrees}C. The results for both the composites and the earlier monolithic material are discussed.
