Discussion of a Coupled Strength Attenuation Model for GFRP Composites in Hydrothermal Environments

摘要: The existing attenuation models for the durability of FRP (fiber-reinforced polymer) composites in hydrothermal environments were compared, and a new coupled strength model with temperature parameter was proposed this paper. A series experiments on GFRP sheets conducted to validate accuracy rationality model. comparison between experimental data calculation results indicated that can fit better effectively reflect convergence phenomenon environments. With included, predict service life at different aging temperatures. According paper, concept method slow-aging time point are put forward, which be convenient evaluation design structures long-term durability.
