| 中文摘要: |
| 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。 |
| 英文摘要: |
| The influence of the adhesion between short fibre and matrix，the orientation and the loading level of short fibre was studied on the dynamics of nylon-NR composite and polyester-CR composite.The result showed that the addition of short fibre desreased tanδ of rubber at low temperature and increased that at high temperature；the higher adhesion between short fibre and rubber，orientation and loading level of short fibre，the greater contribution to the dynamics of the composite；it seemed valuable to evaluate the adhesion in term of the equivalent boudary thickness. |
