in the late period, brittle rupture structures inherited and were superimposed on the early deformation fabrics.
晚期为脆性破裂构造,与早期变形组构具继承、叠加关系。
fibrillation cleavages were observed on torsional fatigue fracture ends of para-aromatic fiber while creep characteristics was observed on the skin of uhmwpe fiber and the brittle rupture in the core.
对位芳纶扭转疲劳断口呈现原纤分裂,uhmwpe纤维皮层呈蠕变特征,芯层有脆性断裂特征。
damage modes of this laminated composite are further examined, which can be clarified into fiber brittle rupture and fiber/matrix debonding, as well as its dependence on strain rate are studied.
