间距为25 mm时,复合材料易发生界面滑脱和端头断裂失效。
3 结论
(1)帘线/橡胶复合材料在不同帘线层接头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。
(2)帘线/橡胶复合材料的帘线层接头搭接段间距为5和15 mm时,试样失效形式主要为搭接处断裂,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,复合材料易发生界面滑脱和端头断裂失效。

(Center for Rubber Composite Materials and Structures,Harbin Institute of Technology at Weihai,Weihai 264209,China)Abstract:The mechanical property and failure modes of cord/rubber composites with different overlap forms and different distance of overlap ction 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 the concave-convex overlap form were the best when the distance of the overlap ction was 5 mm.When the distance of overlap ction of cord/rubber composite material was 5 and 15 mm,the main failure mode of samples were the fracture at the overlap joint,where the stress of the cord layer and rubber layer was the largest.When the distance of the overlap ction was 25 mm,the interface slippage and end fracture failure would easily occur.
