| 中文摘要: |
| 基于轮胎胎面胶配方，研究芳纶短纤维用量和长度对天然橡胶（NR）胶料性能的影响。结果表明：当芳纶短纤维长度为3 mm时，芳纶短纤维用量为2份的胶料的Payne效应最弱，硫化胶的拉伸强度最大，定伸应力和撕裂强度较大，耐磨性能和抗湿滑性能最好；当芳纶短纤维用量为2份时，芳纶短纤维长度为2 mm的胶料的Payne效应最弱，硫化胶的定伸应力和拉伸强度最大，芳纶短纤维长度为3 mm的硫化胶的定伸应力和拉伸强度较大，撕裂强度最大，综合性能最好。 |
| 英文摘要: |
| Based on the formula of tire tread compound，the effects of the amount and length of short aramid fiber on the properties of natural rubber（NR） compound were studied.The results showed that when the short aramid fiber length was 3 mm，the Payne effect of the compound with short aramid fiber amount of 2 phr was the weakest，and the tensile strength of the vulcanizate was the largest，the tensile stress at a given elongation and tear strength were relatively large，and the wear resistance and wet slip resistance were the best.When the short aramid fiber amount was 2 phr，the Payne effect of the compound with short aramid fiber length of 2 mm was the weakest，and the tensile stress at a given elongation and tensile strength of the vulcanizate were the largest.The vulcanizate with short aramid fiber length of 3 mm has larger tensile stress at a given elongation and tensile strength，the largest tear strength，and the best overall performance. |
