Abstract

The results of dynamic testing of alumina samples with different graphene content are presented. The tests were carried out using a split Hopkinson rod according to the “Brazilian test” method at an impact speed of 10 m/s. The optimal value of the graphene content was obtained. The strength characteristics of the alumina nanocomposite with graphene reach a maximum at this value.

石墨烯添加剂对冲击载荷下氧化铝动态强度和失效的影响

摘要

给出了不同石墨烯含量的氧化铝样品的动态测试结果。测试使用分裂霍普金森杆根据“巴西测试”方法以 10 m/s 的冲击速度进行。得到了石墨烯含量的最佳值。氧化铝纳米复合材料与石墨烯的强度特性在此值达到最大值。
