RESEARCH ON THE TENSION-TENSION FATIGUE PERFORMANCE OF GLASS FIBER REINFORCED PLASTIC

Abstract

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
