| 中文摘要: |
| 采用自行研发的测试方法，研究疲劳次数对钢丝帘线/橡胶粘合性能的影响。结果表明：随着疲劳次数的增加，钢丝帘线的抽出力先增大后减小，当疲劳60万次时抽出力达到最大值；抽出钢丝帘线附胶形态无明显差别，且呈螺纹状；附胶越多，抽出力越大。扫描电子显微镜分析表明，钢丝帘线与橡胶界面处的橡胶断面上出现了更多的大粒径填料聚集体颗粒，成为粘合破坏点。 |
| 英文摘要: |
| The effects of fatigue cycles on the adhesion property of steel cord/rubber were investigated by a self-developed test method.The results showed that，as the number of fatigue cycles increased，the pull-out force of steel cord increased at first and then decreased.The pull-out force reached the maximum value at 600 000 cycles.There was no significant difference in the shape of covered rubber on the pulled out steel cord，and it formed screw threads.The more covered rubber，the greater pull-out force.SEM analysis showed that there were larger particles at the interface as the fatigue cycles increased，indicating that the filler agglomerates initiated the adhesion damage. |
