| 中文摘要: |
| 研究不同帘线层接头搭接形式和不同搭接段间距下的帘线/橡胶复合材料的力学特性和失效形式。结果表明：帘线/橡胶复合材料在不同搭接形式下的力学行为具有较大非线性，搭接段间距为5 mm时的凹型凸型搭接试样的综合力学性能最优；帘线/橡胶复合材料的搭接段间距为5和15 mm时，试样主要失效形式为搭接处断裂，此处的帘线层和橡胶层所受应力最大；当搭接段间距为25 mm时，易发生界面滑脱和端头断裂失效。 |
| 英文摘要: |
| The mechanical property and failure mode of cord/rubber composites with different overlap forms and the distance of the overlap section of cord layer joint were studied.The results showed that，the mechanical behavior of cord/rubber composite under different overlap forms was nonlinear，and the comprehensive mechanical properties of concave-convex overlap form were the best when the distance of the overlap section was 5 mm.When the distance of the overlap section of the cord/rubber composite were 5 and 15 mm，the mainly failure mode of samples were fractured at the overlap joint，where the stress of the cord layer and rubber layer was the largest.When the distance of the overlap section was 25 mm，the interface slippage and end fracture failure were easy to occur. |
