| 摘 要： | 采用干法混炼工艺制备了CG混合纤维 (炭纤维和玻璃纤维) /橡胶复合材料, 并在热模拟实验机上测定其蠕变曲线和应力松弛曲线, 对其黏弹性进行了研究。结果表明: 当CG混合纤维体积分数小于15 %时, 可提高橡胶的抗蠕变和抗应力松弛性能; 而当CG混合纤维体积分数大于15 %时, 抗蠕变和抗应力松弛性能开始下降。理论推导表明: CG混合纤维/橡胶复合材料的蠕变与应力松弛在数值上互为倒数关系。

| Abstract: | Carbon fiber and glass fiber (CGfibers) reinforced rubber composite was prepared by using mill mixing
in solid state , and it s creeping curve and st ress relaxing curve were measured using Gleeble 3500 thermal simulator ,and the viscoelasticity was also studied. The result s indicate that , when the volume f raction of CG mixture fibers was less than 15 % , the rubber creep resistance and st ress relaxing resistance were improved ; when the volume f raction of CG mixed fibers was more than 15 % , the rubber creep resistance and st ress relaxing resistance began to decrease. The relationship of creep and st ress relaxation of rubber composites is reciprocal in value. |
