| 摘 要： | 采用海水浸泡-阳光暴晒循环老化的方法来模拟海洋环境中复合材料的实际工作环境,分别评价手糊和真空成型两种玻璃纤维复合材料在海洋环境中的耐久性.通过对老化前后复合材料的质量变化、轴向拉伸强度和面内剪切强度的分析,研究玻璃纤维增强复合材料的老化规律.结果表明:经过湖北武汉和海南三亚70d的自然循环老化,增质量率随时间的增加而增加,干燥试件强度大于湿态试件剩余强度,武汉试件老化剩余强度大于三亚试件剩余强度,手糊和真空成型2种工艺的玻璃纤维增强复合材料表现出不同的老化规律和失效类型.

| Abstract: | Natural cycle aging which contained marinating in seawater and insolating was used to simulate the real work situation for the composites used in the marine environment.The durability of glass fiber reinforced plastic(GFRP) composites was determined under marine environment,and GFRP composites were fabricated by hand lay-up or vacuum assisted resin injection.The aging behavior of GFRP composites samples was studied through the variation of the mass gain and mechanical properties,including tension and in-pla... |
