This article presents selected aspects of an interlaminar shear strength and failure analysis of hybrid fiber metal laminates (FMLs) consisting of alternating layers of a 2024-T3 aluminium alloy and carbon fiber reinforced polymer. Particular attention is paid to the properties of the hybrid FMLs with an additional interlayer of glass composite at the metal-composite interface. The influence of hygrothermal conditioning, the interlaminar shear strength (short beam shear test), and the failure mode were investigated and discussed. It was found that fiber metal laminates can be classified as a material with significantly less adsorption than in the case of conventional composites. Introducing an additional layer of glass composite at the metal-composite interface and hygrothermal conditioning influence the decrease in the interlaminar shear strength. The major forms of damage to the laminates are delaminations in the layer of the carbon composite, at the metal-composite interface, and delaminations between the layers of glass and carbon composites.
本文介绍了由2024-T3铝合金层和碳纤维增强聚合物层交替组成的混杂纤维金属层合板（FML）的层间剪切强度及失效分析的部分内容。特别关注了在金属-复合材料界面处有额外玻璃复合材料中间层的混杂FML的性能。研究并讨论了湿热条件、层间剪切强度（短梁剪切试验）及失效模式的影响。结果发现，与传统复合材料相比，纤维金属层合板可归类为吸附性显著更低的材料。在金属-复合材料界面处引入额外的玻璃复合材料层以及湿热条件会影响层间剪切强度的降低。层合板的主要损伤形式是碳复合材料层、金属-复合材料界面处的分层，以及玻璃和碳复合材料层之间的分层。
