In present research, the flexural properties of glass/epoxy composites reinforced by nanoclay particles (3, 5 and 7 wt.%) under various hybrid thermal cycling and shock loadings (15 and 30 thermal cycles at immediate −70°C and +100°C temperatures) have been investigated. It was found that the flexural strength of 5 wt.% nanoclay/glass/epoxy nanocomposites under 15 and 30 hybrid thermal loadings was enhanced by 19.35% and 20.78%, respectively. Also, after 15 hybrid thermal loadings, the flexural stiffness of 5 wt.% clay/glass/epoxy nanocomposites increased by 9.30% compared to static conditions. More importantly, after 30 hybrid thermal loadings, by adding more filler contents, the flexural stiffness was increased. For instance, at 7 wt.% clay/glass/epoxy nanocomposites, the flexural stiffness enhanced 17.97% compared to neat composite. FESEM morphology images confirmed that presence of optimum filler contents changed the composites inherent properties. Therefore, the outcome of this research can show various remarkable advantages for researchers to apply nanoclay as nanofillers to reinforce composites structures under hybrid thermal cycling and shock applications.

在本研究中，纳米粘土颗粒（3、5和7 wt。％）增强的玻璃/环氧树脂复合材料的弯曲性能在各种混合热循环和冲击载荷下（在-70°C和+ 100°时的热循环（15和30个热循环）下）温度（℃）已被研究。发现在15和30混合热负荷下5重量％的纳米粘土/玻璃/环氧纳米复合材料的弯曲强度分别提高了19.35％和20.78％。同样，在15次混合热载荷之后，与静态条件相比，5 wt。％粘土/玻璃/环氧树脂纳米复合材料的抗弯刚度增加了9.30％。更重要的是，在30次混合热载荷之后，通过添加更多的填料含量，挠曲刚度增加了。例如，在7wt。％的粘土/玻璃/环氧树脂纳米复合材料下，与纯净的复合材料相比，弯曲刚度提高了17.97％。FESEM形态图像证实，最佳填料含量的存在改变了复合材料的固有性能。因此，这项研究的结果可以为研究人员显示出各种显着的优势，他们可以将纳米粘土用作纳米填料，以在混合热循环和冲击应用下增强复合材料的结构。
