Effect of Interfacial Characteristics on the Mechanical Performance of Ceramic-Ceramic Composites.

摘要

The research reported addresses several of the critical issues in the field of ceramic fiber (whisker) / ceramic matrix composites. The overall goal was to understand the complex relationships between processing, interfacial microstructure, and mechanical properties in order to engineer the overall performance of the composites. The composite systems of interest were: (1) SiC whisker / Al2O3 matrix composites, (2) beta-Si3N4 whisker / Si3N4 matrix composites, and (3) SiC continuous fiber / lithium-alumino-silicate matrix composites. Keywords: Ceramic matrix composites, Processing, Interfacial characterization, Mechanical properties. (JES)
