Summary

Unidirectional SIC monofllament-reinforced Si3i4 matrix composites were fabricated by the slurry-coating and filament-winding process, followed by hot pressing. Fracture strength and toughness parameters were assessed in comparison with the matrix material. Composite strengths were controlled by processing-related flaws in the SiC filaments. Moderate improvement in apparent fracture toughness (KQ) and significant improvement in work-of-fracture text (R) were also observed for the unidirectional composites relative to the matrix ceramic.
