摘要
研究了平面三向织物增强橡胶复合材料的偏轴拉伸性能,并与平纹织物增强橡胶复合材料的偏轴拉伸性能进行了对比,同时分析了试样形状(长方形和哑铃形)对织物增强橡胶复合材料的偏轴拉伸的影响。结果表明,平面三向织物增强橡胶复合材料在各个方向的拉伸断裂强度及断裂伸长率变化较小,表现出准各向同性,而平纹织物增强橡胶复合材料则表现为明显的各向异性;哑铃形试样更适合织物增强橡胶复合材料的偏轴拉伸性能测试。
In this paper, the off-axial tensile properties of triaxial-weave-fabric-reinforced rubber composites were studied and a comparative investigation was performed on the off-axis tensile properties between the triaxial and plain-weave-fabric-reinforced rubber composites. Moreover, the influence of sample shape including rectangle shape and dumbbell shape on off-axial tensile of the composite was also analyzed. The results indicated that there was almost no change in the fracture strength and elongation at break of the triaxial-weave-fabric-reinforced rubber composites but a few of changes in their offset angle, showing the quasi-isotropy, whereas the plain-weave-fabric-reinforced rubber composites exhibited evident anisotropy. The dumbbell shape specimen was more suitable for the measurement of the off-axis tensile properties of the composite.
