短纤维－橡胶复合材料动态力学性能研究

Study on Dynamics of Short Fibre-Rubber Composite

研究了短纤维与基质的粘合水平及短纤维的取向、用量等因素对尼龙－天然橡胶和聚酯－氯丁橡胶复合材料的动态力学性能的影响．结果表明：橡胶中加入短纤维可使低温下损耗角正切减小，高温下损耗角正切增大；短纤维与基质粘合程度越高，短纤维取向度越高，填充量越大，则对复合材料的动态力学性能的贡献越大；用等效界面厚度来评价粘合水平有一定意义。

The influence of the adhesion between short fibre and matrix,the orientationand the loading level of short fibre was studied on the dynamics of nylon-NR composite andpolyester-CR composite. The result showed that the addition of short fibre decreased tan δ ofrubber at low temperature and increased that at high temperature; the higher adhesionbetween short fibre and rubbet, orientation and loading level of short fibre, the greatercontribution to the dynamics of the composite;it seemed valuable to evaluate the adhesion interm of the equivalent boudary thickness.
