The present study investigates the effect of halloysite clay nanotubes (HCNT_S) on the mechanical properties of glass reinforced aluminum laminate (GLARE) as a very popular fiber metal laminate (FML). GLARE (3/2) with quasi‐isotropic lay‐up, [Al/[(0°/90°)/(45°/−45°)]s/Al/[(0°/90°)/(45°/−45°)]s/Al], filled with different wt% ofHCNTs (0, 0.25, 0.5, 1, 2, and 3 wt%) were fabricated using hand lay‐up followed by compression molding. Tensile, flexural, and impact properties of the fabricated GLAREs were evaluated. The failure of the specimens was examined using field emissionscanning electron microscope (FE‐SEM), energy‐dispersive X‐ray spectroscopy (EDX) and visual inspection. Test results demonstrated that the incorporation of HCNTs improves the mechanical properties of GLARE. Among the studied wt%, the inclusion of 1 wt% of HCNTs to GLARE leads to maximum improvements of 35.67%, 8.50%, 28.85%, 50.47%, 50.27%, 30.43%, and 51.52% in tensile strength, tensile strain, Young's modulus, modulus of toughness, flexural strength, flexural strain, and impact strength, respectively, was attained by adding 1 wt% of HCNTs to GLARE compared to pristine GLARE. Meanwhile, increasing HCNT_S content to 3 wt% reverse the trend. FESEM showed that, HCNT_S are well dispersed in epoxy. However, a higher weight fraction of HCNT_S in epoxy, that is, 3 wt% leads little agglomerations.

纳米填料改善GLARE力学性能的实验研究

本研究调查了埃洛石粘土纳米管（HCNT _S）作为一种非常流行的纤维金属层压板（FML）的玻璃增强铝层压板（GLARE）的机械性能 具有准各向同性叠置的GLARE（3/2），[Al / [（0°/ 90°）/（45°/ -45°）] s / Al / [（0°/ 90°）/（45 [°/ −45°）] s / Al]的填充方法是手工叠层，然后压制成型，填充不同重量百分比的HCNT（0、0.25、0.5、1、2和3重量％）。评估了制成的GLARE的拉伸，弯曲和冲击性能。使用场发射扫描电子显微镜（FE‐SEM），能量色散X射线光谱仪（EDX）和目测检查了样品的失效。测试结果表明，加入HCNT可以改善GLARE的机械性能。在研究的wt％中，将1 wt％的HCNT包含到GLARE中可最大程度地提高35.67％，8.50％，28.85％，50.47％，50.27％，30.43％和51。与原始GLARE相比，通过向GLARE中添加1wt％的HCNT，分别获得了52％的拉伸强度，拉伸应变，杨氏模量，韧性模量，弯曲强度，弯曲应变和冲击强度。同时，增加HCNT_S含量为3wt％则逆转了这种趋势。FESEM表明，HCNT _S很好地分散在环氧树脂中。但是，HCNT _S在环氧树脂中的重量分数较高，即3 wt％，导致很少的团聚。
