Abstract
The mechanical properties at high temperature of Si3N4/BN fibrous monolithi c ceramics were tested. The flexural strength of SiC whisker reinforced Si3 N4/BN fibrous monolithic ceramics from 25 degreesC to 1200 degreesC were in vestigated. The strength degraded slowly from 1000 degreesC to 1200 degrees C which was different to Si3N4 monolithic ceramics. The creep behaviors of the material at different temperatures were characterized. Si3N4/BN fibrous monolithic ceramics possess high creep resistance. The chemical compositio n and microstructure of the composites were analyzed by XRD and SEM. (C) 20 01 Kluwer Academic Publishers.
