摘要

摘要: 采用十字形试件,在双轴拉伸条件下研究了尼龙帘线-橡胶复合材料单层板纵向定载荷对横向力学性能的影响和横向定载荷对纵向力学性能的影响。实验结果表明:纵向拉伸载荷对尼龙帘线-橡胶复合材料的横向拉伸力学性能有很大的影响。随着纵向拉伸载荷的增加,横向应力应变关系发生了很大的变化;横向拉伸强度先上升然后又下降;而其断裂变形和变形能却逐渐减小。横向拉伸载荷对尼龙帘线-橡胶复合材料的纵向拉伸力学性能影响却很小。这可能与材料纵向和横线拉伸性能差异太大有关。

Abstract: The effects of longitudinal constant tensile loads on transverse behaviors and transverse loads on longitudinal behaviors of a single ply of nylon cord-rubber composite are studied respectively under biaxial tensile condition with cruciform specimens in this paper. Experiment results indicate that the effects of longitudinal constant tensile loads on transverse tensile behaviors are obvious. Transverse stress-strain behaviors change largely compared with uniaxial transverse tensile behavior; transverse tensile strength increases first and then decreases; fracture strain and deformation energy decrease by increasing of longitudinal tensile loads; the results are induced by common actions of rigidification and damnification caused by longitudinal tensile loads. However, the effects of transverse constant tensile load on longitudinal tensile mechanical behavior are not distinctive. It can be ascribed to large discrepancy between longitudinal and transverse properties of nylon cord-rubber composite.
