摘要：

研究了平面三向织物及其增强橡胶复合材料的撕裂性能，分别对预切口平行于平面三向织物中某一组纱线和平行于平面三向织物中相邻两组纱线角平分线方向2种情况下的撕裂性能进行研究，并与平纹织物增强橡胶复合材料进行了对比。结果表明，平面三向织物及其增强橡胶复合材料的撕裂过程可分为初始阶段、预切口张开阶段和撕裂口扩展阶段等3个阶段，分别与撕裂载荷?位移曲线低模量区、高模量区和震荡区相对应；预切口与纱线平行时，平面三向织物及其增强橡胶复合材料具有较高的撕裂载荷和较大撕裂起始位置；相对于平纹织物，平面三向织物及其增强橡胶复合材料沿两种预切口撕裂载荷差异较小。

Abstract:

This paper reported an investigation on the tearing performance of triaxial woven fabric and its reinforced rubber composites. The study was aimed at two cases， including the pre-incision along the yarn direction and the pre-incision along any two groups of yarn angle bisectors. A comparative investigation was also carried out with the plain weave fabric reinforced rubber composites. The variation laws in the tearing load and tearing damage characteristics of the specimens were analyzed. The results indicated that the tearing process of the triaxial woven fabric and its reinforced rubber composites could be divided into three stages： the initial stage， the pre?notch opening stage and rip expansion stage， which were related to low modulus area， high modulus area and shock area， respectively. When the pre-cut was parallel to the yarn， the triaxial woven fabric and its reinforced rubber composite exhibited a higher tear load and tear initiation position. Compared to plain weave fabrics， the triaxial woven fabric and its reinforced rubber composites showed a much smaller difference in the tear load along the two pre?cuts.
