采用CEAST公司冲击试验仪研究了PP/HDPE/FPDM三元共混材料的冲击过程,测定了在不同橡胶含量和不同基体韧性等条件下,裂纹扩展力(F)、冲击断裂时间(t)、冲击断裂功(E)和裂纹平均扩展速度(V)等参量的变化规律和相互关系。
The impact process of PP / HDPE / FPDM ternary blends was studied by CEAST Impact Tester, and the effects of crack growth force (F), impact fracture time (t) Impact fracture work (E) and crack propagation velocity (V) and other parameters of the law of change and correlation.
