摘要：对压缩非石棉短纤维增强橡胶密封材料 (简称CFS材料 )蠕变理论和试验进行了研究。采用弹簧 粘壶模型推导蠕变方程和通过最小二乘法拟合试验数据的分析表明 ,CFS材料的蠕变与大部分固体材料的短期蠕变类似 ,符合一般对数变化规律 ;模型计算值与试验值具有较好的一致性 ,CFS材料的蠕变主要发生在应力作用的最初 5 0 0min内 ,其后变缓慢。
The creep theory and experiment of compressed non-asbestos fiber-reinforced sheet (CFS) were investigated.The creep equation derived from the spring-viscopot and the analysis of the experimental data fitted with least square method showed that the creep of CFS was similar to that of most solid materials in the short term and obeyed the general logarithmic rule;the calculated result from the model agreed well with the experimental result;and the creep of CFS occured basically in the first 500 min after the stress was applied,and then slowed down.
