平面三向织物及其增强橡胶复合材料的顶破性能研究
|
摘要
采用实验方法研究了平面三向织物(TWF)及其增强橡胶复合材料(TWFR)的顶破性能,探讨了冲头速度(100、300、500 mm/min)和形状(圆锥形、半球形和圆柱形)对顶破性能的影响。同时对比分析了平纹织物(PWF)及其增强橡胶复合材料(PWFR)的顶破性能。结果表明,较钝的冲头产生较高的荷载-位移斜率,较大的断裂载荷和较小的初始损伤位移;试样的破坏形态表明TWF显示出稳定的结构,并且在破裂后损伤不易扩展;随着冲头速度的增大,TWFR的载荷-位移曲线斜率和破坏载荷均有所升高,但初始损伤位移减小;TWF的载荷-位移曲线变化不明显。
In this paper, the bursting properties of triaxial weave fabric(TWF) and its reinforced rubber composite(TWFR) were evaluated, and the effect of bursting speeds and shapes including conical, hemispherical and plane impactors on the bursting properties were investigated. Moreover, a comparative study was conducted for TWF and TWFR with plain woven fabric and its reinforced rubber composites. The results indicated that blunter impactor generated the higher load-displacement slopes, larger fracture loads, and smaller initial damage displacements. The bursting morphologies of these samples indicated that TWF had a stable structure, and the damages were not easily expanded after breakage. As the bursting speed increased, the slope of load-displacement curve and fracture load of TWFR increased, but the initial damage displacement decreased. There was no significant change observed in the load-displacement curves of TWF.
