The application of nanomaterials as a strengthening agent in the fabrication of polymer nanocomposites has gained significant attention due to distinctive properties which can be utilised in structural applications. In this study, reduced graphene oxide (r-GO) and montmorillonite (MMT) nanoclay were used as filler materials to fabricate hybrid epoxy-based nanocomposites. The synergistic effect of nanomaterials on flammability and mechanical behaviour of nanocomposites were studied. Results revealed that the addition of nanofiller showcases 97% and 44.5% improvement in tensile and flexural strength. However, an increment in the percentage of filler material over 0.3% exhibits a decremental mechanical property trend. Likewise, the addition of nanofiller increases the nonignition timing of the glass-fibre-reinforced epoxy composites. Fracture surface morphology displays the occurrence of the ductile fracture mechanism owing to the presence of hybrid fillers.

r-GO-MMT混合纳米填料在提高环氧/玻璃纤维复合材料的强度和阻燃性中的应用

纳米材料作为增强剂在聚合物纳米复合材料的制造中的应用由于其可用于结构应用的独特性能而受到了广泛的关注。在这项研究中，还原的氧化石墨烯（r-GO）和蒙脱土（MMT）纳米粘土被用作填充材料，以制造基于环氧树脂的杂化纳米复合材料。研究了纳米材料对纳米复合材料的可燃性和力学行为的协同作用。结果表明，纳米填料的添加显示出抗张强度和抗弯强度分别提高了97％和44.5％。然而，填充材料百分比的增加超过0.3％表现出递减的机械性能趋势。同样，添加纳米填料会增加玻璃纤维增​​强环氧复合材料的非着火时间。
