摘要:
纤维增强复合材料由于其耐腐蚀性好、质量轻和比强度高等优点被广泛应用于海洋工程.研究真空灌注制作的乙烯基酯玻璃纤维复合材料在南海环境下,在室温和60 ℃高温的海水中浸泡不同时间的试样进行玻璃转化温度和拉伸强度测试.试验结果表明:材料的玻璃转化温度随着浸泡的时间增加而下降.其拉伸强度变化分为三个阶段:第一个阶段随时间增加而上升; 第二阶段缓慢降低; 第三个阶段以较快的速率降低.并给出了拉伸强度随浸泡时间变化三个阶段的指数拟合函数.从试验结果来看:乙烯基酯玻璃纤维复合材料具有很好的耐久性.
Abstract:
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.
