| 中文摘要: |
| 本文就尼龙、聚酯短纤维的长度对尼龙-天然橡胶以及聚酯-氯丁橡胶复合材料的物理性能和溶胀性能的影响进行了理论研究。实验结果表明：这两种短纤维橡胶复合材料的撕裂强度、20%定伸应力随短纤维长度增加而增大，抗溶胀能力增强；拉伸强度则在短纤维最佳长径比条件下最好。尼龙、聚酯短纤维经D法预处理后，其复合材料的各项性能均有较大提高。 |
| 英文摘要: |
| A study was made on the influence of length of nylon and polyester fibres on the physical and swelling properties of nylon/NR and polyester/CR composites. The experiment results showed that the tear strength，the modulus at 20% and the swelling resistance increased as the length of the fibre increased；the tensile strength was the best with the optimum LID ratio of the short fibre. The properties of the composites increased significantly when the nylon and polyester fibres were pretreated with method D. |
