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。 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 L/D ratio of the short fibre. The properties of the composites increased significantly when the nylon and polyester fibres were pretreated with method D.
