Durability of fiber metal laminates (FMLs) is a very essential issue when using in humid and marine environments. Therefore, water barrier properties and impact damage resistance of glass aluminum reinforced epoxy (GLARE) filled with various types of nanofillers were investigated in this work. Silica (SiO₂), titanium oxide (TiO₂), aluminum oxide (Al₂O₃), copper (Cu) and aluminum (Al) nanofillers were incorporated with 1 wt% into composite laminate core of GLARE. Impact tests were performed under dry, distilled and seawater conditions. Results showed that water absorption of nanofilled GLARE is lower than that of pristine GLARE in both distilled and seawater. After distilled and seawater conditioning, a decrease in impact strength has been identified for all specimens. In comparison with pristine GLARE, nanofilled GLARE shows an improvement in impact resistance under dry, distilled and seawater conditions. GLARE filled with SiO₂ nanoparticles exhibits the highest impact strength under dry conditions with an enhancement of 14.2 %. However, TiO₂ nanoparticles exhibits the highest impact strength under distilled and seawater conditions with an enhancement of 20.9 % and 20.5 %, respectively. Visual inspections and SEM images showed that adding nanoparticles improves adhesion between epoxy matrix/fiber in nanocomposite and enhances the bonding between the nanocomposite and the outer aluminum sheets.

在潮湿和海洋环境中使用时，纤维金属层压板（FML）的耐久性是非常重要的问题。因此，在这项工作中研究了填充有各种类型纳米填料的玻璃铝增强环氧树脂（GLARE）的阻水性能和抗冲击破坏性。二氧化硅（SiO ₂），氧化钛（TiO ₂），氧化铝（Al ₂ O ₃），将铜（Cu）和铝（Al）纳米填料以1 wt％的含量掺入GLARE的复合层压板芯中。冲击试验在干燥，蒸馏和海水条件下进行。结果表明，在蒸馏水和海水中，纳米填充GLARE的吸水率均低于原始GLARE。经过蒸馏和海水调节后，所有样品的冲击强度均降低。与原始GLARE相比，纳米填充GLARE在干燥，蒸馏和海水条件下的抗冲击性有所提高。充满SiO ₂纳米颗粒的GLARE在干燥条件下表现出最高的冲击强度，增强了14.2％。但是，TiO ₂纳米颗粒在蒸馏和海水条件下显示出最高的冲击强度，分别提高了20.9％和20.5％。视觉检查和SEM图像显示，添加纳米颗粒可改善纳米复合材料中环氧基质/纤维之间的粘合力，并增强纳米复合材料与铝外层之间的粘合力。
