Mechanical Properties Of SiC/Si3N4 Laminates

Two reports describe tests to determine mechanical properties of laminates made of reaction-bonded silicon nitride matrices reinforced with 30 volume percent of aligned silicon carbide fibers. Emphasizes different aspects of topic. One focuses on behavior related to strength at ambient temperature; other focuses on strength after exposure to high temperatures. Overall, results indicate that composites are candidates for use at high temperatures; for example, as components of heat engines.
