critical fiber length meaning in English

临界纤维长度

In addition , a new analytical method was used to solve the shear strength of the fiber / epoxy interface . the result showed good agreement with that from the kelly - tyson equation . meanwhile , according to the sfc tests of the single fiber reinforced epoxy matrix composites treated by four types of surface treatments , the interfacial adhesion conditions were estimated by critical fiber length , interfacial shear strength and single fiber microdamge mode
此外，文中对单纤维复合材料断裂实验运用了新的解析方法，求解了玻璃纤维环氧复合材料界面的剪切强度，与kelly - tyson等式方法求得的界面剪切强度有着很好的一致性；同时，对四种不同表面处理剂处理的单纤维复合材料断裂实验进行了分析，从临界纤维长度、界面剪切强度和单纤维断裂实验中纤维断点周围基体形貌评价了界面的粘结情况。
