In this research, effect of Al₂O₃ nanofillers on mechanical, wear, and hardness characteristics of basalt/epoxy laminate composites were carried out. Composite laminates of basalt/epoxy with different percentage of Al₂O₃ nano fillers were manufactured by Hand layup method. Mechanical Properties which includes tensile strength, inter laminar shear strength (ILSS), flexural strength, impact strength, and hardness were investigated as per ASTM standards. Wear tests were carried out for different loads with different sliding velocities keeping sliding distance constant. It was observed that flexural strength and ILSS increases for small percentage of nanofillers, whereas tensile strength deteriorates with increase in percentage of fillers and hardness increases with increase in percentage of fillers. The wear results indicates, the addition of Al₂O₃ nanofillers significantly reduces the wear loss of basalt/epoxy composites. Fractured and worn surfaces were analyzed with scanning electron microscopy images which establishes a good agreement with the obtained results.

Al2O3纳米填料在玄武岩/环氧树脂复合材料中的作用：力学和摩擦学性能

在这项研究中，Al ₂ O ₃纳米填料对玄武岩/环氧层压复合材料的机械，磨损和硬度特性产生了影响。具有不同百分比的Al ₂ O ₃的玄武岩/环氧树脂复合层压板纳米填料是通过手糊法制备的。根据ASTM标准研究了包括拉伸强度，层间剪切强度（ILSS），弯曲强度，冲击强度和硬度在内的机械性能。在保持滑动距离恒定的情况下，针对不同载荷以不同滑动速度进行了磨损测试。观察到，对于小百分比的纳米填料，弯曲强度和ILSS增加，而抗张强度随着填料的百分比的增加而劣化，并且硬度随着填料的百分比的增加而劣化。磨损结果表明，Al ₂ O _3的添加纳米填料显着降低了玄武岩/环氧树脂复合材料的磨损量。用扫描电子显微镜图像分析断裂和磨损的表面，这与所获得的结果建立了良好的一致性。
