EEA Poor Fatigue Resistance
ظاهرة المشكلة
EEA product fatigue life <10⁴ cycles, below the 10⁵ cycles requirement
تحليل الأسباب
EEA elastic recovery insufficient, plastic deformation accumulates with each cycle; crosslinking degree low, fatigue crack propagation fast
الحل
1) Increase crosslinking degree to improve recovery and reduce accumulated deformation; 2) Select high-molecular-weight grades to increase the fatigue threshold; 3) Product design to reduce stress concentration
الخلاصة الأساسية
Poor fatigue resistance is caused by insufficient recovery and fast crack propagation; increasing crosslinking is key
