Fiber-reinforced polymer (FRP) composites are increasingly used in marine engineering due to their excellent corrosion resistance, light weight and high specific strength. This paper reports an investigation on the behavior of vacuum infused glass fiber-reinforced vinyl ester (GFRP) composites. The specimens were immersed in simulated South China Sea water at room temperature and 60 ℃ for different durations and their tensile strength and glass transition temperature (Tg) were tested. Results indicate that the Tg of the specimens decreases as the immersion time increases. The change of tensile strength exhibits three stages: The tensile strength increases to a maximum value in the first stage, then reduces slowly in the second stage, and reduces more rapidly in the third stage. Data regression analyses were conducted and an exponential model is presented. The test results indicate that the GFRP exhibits good durability.
