Abstract: We report the results of testing the dynamic strength of Al$_2$O$_3$ nanoceramics with different concentrations of five-layer graphene under the action of a high-current nanosecond electron beam and a high-voltage electric discharge of the same nanosecond duration. It is found that, under pulsed loading, an increase in the graphene content in the composite increases the brittleness of the nanocomposite.
Keywords: metal ceramic composite, graphene, high-current electron beam, high-voltage discharge.
