摘　　要：采用压片工艺和刷涂工艺制备了碳纤维/双马来酰亚胺(T300/QY8911)嵌入式共固化复合材料阻尼结构(ECCDS)试件。对T300/QY8911复合材料阻尼结构试件的吸湿特性进行了研究,获得了吸湿率与阻尼层厚度的关系;对两种工艺制备的复合材料吸湿处理后的层间结合性能进行了研究,分析了阻尼层厚度与层间最大剪切应力的关系。结果表明:含穿孔黏弹性阻尼层的ECCDS能明显提高吸湿处理后的层间结合性能,为ECCDS的理论设计和应用研究奠定了基础。The carbon fiber/bismaleimide(T300/QY8911)embedded co-cured composite damping structure(ECCDS)specimens were manufactured by pressed-film process and brush coating process.The moisture absorption properties of T300/QY8911 composite damping structure specimens were studied,and the relationship between moisture absorption rate and the thickness of damping layer was obtained.The interlayer bonding properties of moisture absorption treated composites made by the two processes above were investigated,and the relationship between the thickness of damping layer and the maximum interlamination shear stress was analyzed.Results show that the ECCDS with perforated viscous-elastic damping layer can increase the interlaminar bonding properties after moisture absorption treatment,and provide a foundation for the theoretical design and application research of ECCDS.
