摘　　要：以ENF试验为基础,通过制作不同长度的芳纶短纤维薄膜为粘接层界面的碳纤维/铝层状复合结构试件,并置于同一加速腐蚀环境中,研究了芳纶短纤维对碳纤维/铝层状复合结构力学性能及抗电偶腐蚀性能的影响。试验结果表明芳纶短纤维薄膜有效提高了碳纤维/铝层状复合结构的断裂性能与抗电偶腐蚀性能,可为复合材料工程应用中的电偶腐蚀防护提供参考。Based on the ENF test,the self-prepared carbon fiber/aluminum laminated composite structure samples with different lengths of aramid short fiber films as adhesive layer interface were placed in the same accelerated corrosion environment to study the effect of aramid short fiber on the mechanical properties and galvanic corrosion resistance of carbon fiber/aluminum laminated composite structure.The experimental results show that the aramid short fiber film can effectively improve the fracture properties and the galvanic corrosion resistance of the carbon fiber/aluminum laminated composite structure;it can provide a reference for the protection of galvanic corrosion in composite engineering application.
