Silicon carbide matrix composite with increased fracture toughness and thermal shock resistance

Kyoto University, Kyoto, Japan

TECHNOLOGY SUMMARY

Ceramic matrix composites are expected to replace the conventional alloys/metal components in the aircraft engines. While maintaining its thermal shock resistance and fracture toughness, this novel SiC fiber-reinforced SiC material is free from fiber/matrix interface thus does not require a costly process to control interface thickness to prevent its oxidation.

Primary Application Area: Defense & Transportation

Technology Development Status: Prototype

Technology Readiness Level: TRL 3

FIGURES OF MERIT

Value Proposition: This new SiC matrix composite does not have fiber/matrix interface that is weak against the oxidative degradation. It does not require a costly process to control the interface thickness that is a bottleneck for large-scale production.
