Poor Fatigue Resistance of CMC
문제 현상
Fatigue life of CMC products <10⁴ cycles, lower than the 10⁵ cycles requirement
원인 분석
CMC elastic recovery is insufficient and plastic deformation accumulates each cycle; crosslinking degree is low and fatigue crack propagates fast
해결 방법
1)Increase crosslinking degree to improve recovery and reduce accumulated deformation; 2)Select high-molecular-weight grade to increase fatigue threshold; 3)Product design to reduce stress concentration
핵심 요약
Poor fatigue resistance is caused by insufficient recovery and fast crack propagation; increasing crosslinking is the key
