1) environmental aging
环境老化
1.
The environmental aging behaviors of a vinyl ester (VE) resin in distilled water, 3%NaCl aqueous solution, 5%H_2SO_4 aqueous solution and 10%NaOH aqueous solution were studied in laboratory.
本论文研究了实验室模拟环境(湿热、酸、碱、盐)下，乙烯基酯树脂(VE)浇注体的环境老化行为，测定了浇注体在65℃和95℃蒸馏水、3％NaCl水溶液、5％H_2SO_4水溶液和10％NaOH水溶液中的吸湿特性，分析了环境因素对其静态和动态力学性能的影响以及该树脂浇注体在不同介质中的老化机理，同时，也研究了在65℃3％NaCl水溶液中的碳纤维／乙烯基酯树脂(CF／VE)复合材料的电化学腐蚀行为，分析了复合材料本身的电化学特性以及与金属偶合对其腐蚀行为产生的影响。
