INVESTIGATION OF LONG-TERM CREEP BEHAVIOR OF GLASS FIBER REINFORCED PLASTICS WITH DIFFERENT PLY LAYERS

Abstract

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
