中文摘要：
实验研究了温度与湿度因素对玻璃微珠增强硬质聚氨酯复合泡沫塑料（玻璃微珠／RPUF）黏弹力学性能的影响。结果表明，湿度对黏弹力学性能有显著的影响，随着湿度的增加，玻璃微珠／RPUF的储能模量减小，刚度下降，力学损耗因子值增加，蠕变柔量增大，柔韧性增强。湿度对玻璃微珠／RPUF弯曲蠕变性能的影响具有类似于时间一温度等效原理的等效关系，并给出了60℃／50％RH参考温湿度下玻璃微珠／RPUF的蠕变主曲线和平移因子。
英文摘要：
The viscoelastic behavior of glass microsphere reinforced rigid polyurethane syntactic foams （glass microsphere/RPUF） under different temperatures and humidities was investigated. The experimental results show that temperature and humidity have an obvious effect on viscoelastic behavior of glass microsphere/RPUF. With increasing the relative humidity, the loss factors value increases while the storage modulus decreases. Under the same temperature, the creep compliance increases as humidity increasing. Using the time- humidity super-position principle, each master curve can be shifted to collapse into the reference master curve by introducing shift factors for humidity, and the master curves of creep compliance at reference temperature（60 C） and humidity（50 % RH） are put forward.
