本文研究了由短切玻璃纤维和乙烯基酯树脂组成的玻璃纤维增强复合材料的动态粘弹性和弯曲蠕变性能。在不同的应力和温度条件下进行了弯曲蠕变试验。另一方面，在25 μ m振幅下在不同温度下进行动态粘弹性测试。将时间-温度叠加原理应用于试验结果，得到了GFRP的蠕变柔量、储能弹性模量、损耗弹性模量和损耗角正切的主曲线。此外，从弯曲蠕变数据计算的时间-温度偏移因子的温度依赖性与从动态粘弹性数据计算的一致。在此基础上，利用动态粘弹性试验结果对GFRP的蠕变柔量进行了预测。
This paper is concerned with the prediction of dynamic viscoelastic and flexural creep behavior for GFRP consisting of short fiberglass and vinyl ester resin. The flexural creep tests were carried out under the various conditions of stress and temperatures. On the other hand, the dynamic viscoelastic tests were carried out under the various temperatures at 25 um vibration amplitude. The master curves of creep compliance, storage elastic modulus, loss elastic modulus and loss tangent of GFRP were obtained by applying the time-temperature superposition principle to these experimental results. Furthermore, the temperature dependence of the time-temperature shift factors calculated from the flexural creep data was in agreement with that calculated from the dynamic viscoelastic data. On the basis of these results, the creep compliance of GFRP is predicted by using the experimental results of dynamic viscoelastic tests in this paper.
