| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
