阻坝扩张式复合机头结构参数对短纤维补强橡胶复合材料性能的影响

研究阻坝扩张式复合机头的结构参数包括扩张比、扩张角、阻坝间隙、定型流道段长度、收敛角和过渡流道段长度对短纤维补强橡胶复合材料性能的影响。结果表明：当扩张比为5、扩张角为150°、阻坝间隙为4 mm、定型流道段长度为50 mm、收敛角为120°、过渡流道段长度为30 mm时，短纤维补强橡胶复合材料的综合物理性能较好，且各向异性明显。;The effects of structure parameters of dam-expansion-complex die，including expansion ratio，expansion angle，dam clearance，molding channel length，convergence angle and transition channel length，on the properties of short fiber/rubber composite were studied experimentally.The results showed that，when the expansion ratio was 5，the expansion angle was 150°，the dam clearance was 4 mm，the molding channel length was 50 mm，the convergence angle was 120° and the transition channel length was 30 mm，the comprehensive physical properties of the composite were better，and the anisotropy of the composite was distinct
