摘要
碳纤维增强树脂基复合材料是一种性能优异的复合材料,已在航空、航天、航海等领域得到了普遍应用。以热压釜工艺制备的单向T700/环氧复合材料为研究对象,探究其在海洋环境下的吸水特性(吸水率及扩散特性等)。首先,研究了该复合材料在海水和蒸馏水中的吸水率随时间的变化情况;其次,对不同尺寸试样在海水中的吸水率进行了对比分析;最后,对比研究了复合材料在20℃、40℃、60℃、70℃、80℃的海水中吸水率的变化情况。结果表明,蒸馏水在复合材料中的扩散速率比海水快,初期复合材料在蒸馏水中的吸水率低于在海水中的吸水率,但随着时间的延长,后期复合材料在蒸馏水中的吸水率逐步高于在海水中的吸水率;试样尺寸对复合材料在海水中的吸水率影响不大;海水的温度越高,复合材料的吸水率越大。研究成果有助于更合理地设计复合材料,并有效地应用于海洋环境中。
Carbon fiber reinforced plastic which been applied in aviation,spaceflight,navigation and etc.is a kind of high performance composites.While a unidirectional 1700/Epoxy composites manufacturing by an autoclave process in the marine environment,the characteristics of water absorbency including absorption and diffusion were investigated in the paper.Firstly,the variances of absorption ratio of the composites about the immersing time in the marine water and distilled water were analyzed.Secondly,the variances of absorption ratio about the size of the composite samples immersing in the marine water were investigated.Thirdly,the a comparing study about the variances of absorption ratio of the composite immersing in the marine water with 20 ℃,40 ℃,60 ℃,70 ℃ and 80 ℃ was conducted.Results show that there is a higher diffusion ratio of distilled water in the composite.There is a higher absorption ratio of the composite immersing in the marine water than that in the distilled water at beginning.However,a reverse phenomenon appears with the increasing of immersing time.There isn't a significant influence of sample size on the absorption ration.The higher temperature of the marine water,the greater absorption ratio of the composite is observed.These results would be helpful for the design of composite,and improving the application in ocean environment.
