摘要/Abstract

摘要： 随着玻璃纤维增强复合材料的广泛应用,如何正确地分析其蠕变特性已成为最为迫切的课题之一。但由于实验方法和理论研究的不成熟性,致使玻璃钢长期性能的研究发展较为缓慢。在前人研究的基础上,制备不同铺层角度的玻璃钢试样,探究蠕变柔量随服役时间的增加而改变的特性,并建立相应的双变参理论模型,用理论公式拟合实验数据,并比较不同铺层角度蠕变性能的差异性。结果表明理论模型与实验数据契合度较高。

Abstract: With the wide application of glass fiber reinforced composites, the study of its creep properties has been one of the most significant projects. Meanwhile, the study of long-term performance of glass fiber reinforced plastics develops slowly, owing to the immaturity of experimental methods and theoretical researches. In this paper, based on the previous research, glass fiber reinforced plastics samples with different ply layers were prepared to explore the regularities of creep compliance's change with the increasing service time . The corresponding theoretical model with two parameter variables was established. The experimental data was fitted by the theoretical formula. The differences in creep properties of different ply layers were compared. The results show that the model and experimental data agree well with each other.

Key words: FRP, different ply angles, theoretical model, creep compliance
