摘要： 采用大变形、非线性有限元分析方法,以单根纤维帘线的大位移(0~2.5 mm)拔出为例,对橡胶-纤维复合材料不同温度下的界面力学性能进行了数值分析,得到了相应的应力场分布和拔出载荷的变化.模拟结果表明,在纤维拔出时,橡胶-纤维复合材料界面的端部出现剪应力集中,并随着温度变化而变化.拔出载荷与试验结果对比,在中、低温度区域内,具有较好的一致性.

Abstract: The interfacial mechanical properties of fiber-rubber composite were studied at different temperatures with nonlinear FEA to analyze the large deformation of a single cord or fiber that was pulled out of the composite by 2.5 mm. The distribution of normal stress in fiber and interfacial shear stress were obtained as well as the axial pull-out force. The results showed that peak shear stress occurs at the interfacial end and changes with different temperatures. Moreover, the FEA result of pulling-out force showed a good agreement with experimental result at low/moderate temperatures.
