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.
Keywords:
ceramic composite, graphene, split Hopkinson rod, Brazilian test.
