摘　　要：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。By CEAST impact test machine ,impact process of PP/HDPE/EPDM ternary blends were studied. Under conditions of different rubber content and the matrix toughness, crack extending force, impact break time, impact break power and crack average intending velocity were determined, and its various law and interrelationship were discussed.
