摘要/Abstract

摘要： 本文以乙烯基酯树脂和环氧树脂为基体,制备玻璃纤维增强树脂基复合材料拉-拉疲劳试件,研究应力振幅、铺层方式、树脂体系对树脂基复合材料疲劳性能的影响。结果表明,随着应力振幅的增加,GFRP 试件的拉伸模量呈现单调下降; 随着玻璃纤维布层数的增加,GFRP 拉-拉疲劳性能会大幅下降; 环氧树脂复合材料的疲劳性能要明显优于乙烯基酯树脂复合材料。

Abstract: The author prepared GFRP Specimen by way of vacuum assisted resin infusion process,using vinyl ester resin,epoxy resin and glass fiber as raw material in this paper. Through the dynamic fatigue test,this paper analyzes the influence of stress amplitude,layer mode and resin system on the tension-tension fatigue performance of GFRP. The result show that the tensile modulus of the GFRP decreased monotonously along with the increasing of the stress amplitude. Furthermore,the tension-tension fatigue performance of GFRP will be significantly decreased as the number of layers increasing. In addition,the fatigue performance of composites with epoxy resin matrix is significantly better than the one with vinyl ester resin matrix.

Key words: GFRP, tension-tension fatigue, residual stiffness, S-N curve
