Fatigue fracture of aluminum wires due to Aeolian vibrations (high-cycle fatigue) is one of the severe problems in the high-capacity conductors of the power transmission lines. On the other hand, previous studies have shown that graphene can significantly increase aliminum’s mechanical and electrical properties. In this regard, this research has studied the high-cycle fatigue (HCF) of Al-0.5 wt% GNPs composite using experimental methods. Quasi static and high-cycle fatigue tests were performed at room and elevated temperatures and material parameters of the Basquin's equation were derived. A fractographic analysis of the fractured samples was carried out using field emission scanning electron microscopy (FE-SEM). The results showed that composite has better hardness and tensile strength than pure aluminum, while its elongation was decreased. At room temperatures, the fatigue life of the composite was increased by 234 % and 44 % at low and high stress levels, respectively. While at elevated temperatures, 146 % and 130 % increase in fatigue life were obtained at low and high stress levels, respectively.

风力振动引起的铝线疲劳断裂（高周疲劳）是输电线路大容量导线中的严重问题之一。另一方面，先前的研究表明，石墨烯可以显着提高铝的机械和电气性能。在这方面，本研究使用实验方法研究了 Al-0.5 wt% GNPs 复合材料的高周疲劳 (HCF)。在室温和升高的温度下进行准静态和高周疲劳试验，并推导出 Basquin 方程的材料参数。断口的 断口分析  使用场发射扫描电子显微镜 (FE-SEM) 对样品进行了分析。结果表明，复合材料比纯铝具有更好的硬度和抗拉强度，但延伸率有所下降。在室温下，复合材料的疲劳寿命在低应力和高应力水平下分别增加了 234% 和 44%。在高温下，低应力和​​高应力水平下的疲劳寿命分别增加了 146% 和 130%。
