摘　　要：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.
