摘　　要：根据聚合物基复合材料的粘弹性,认为湿度与温度、应力等因素对材料特征时间的影响相似,具有等效性。依据自由体积膨胀理论,推导了温度-湿度联合位移因子的表达式,提出了时间-温度-湿度等效原理。应用时间-温度-湿度等效原理,提出了构造材料参考温湿度下蠕变主曲线的2种实验路径。Considering the viscoelasticity of polymeric matrix composites（PMC）,it is thought that the effect of relative humidity on the character time of PMC is similar to that of temperature and stress.With the free volume expansion theory,time-temperature-humidity superposition principle（TTHSP） was proposed and the expression of temperature-humidity combined shift factor was deduced.Based on the TTHSP,two experimental paths of building the master curves of creep compliance at reference temperature and humidity for PMC were put forward.
