▎ 摘　　要

A hybrid carbon material of the composition few-layer graphene/detonation nanodiamonds synthesized under the conditions of self-propagating high-temperature synthesis was first tested as a modifying additive in creating of a composite material based on aluminum. It was found that the use of 0.25 mass. % of the hybrid material made it possible to increase the hardness of the metal composite up to 2 times compared to the original aluminum while maintaining the density identical to the original aluminum and a sufficiently high thermal conductivity of about 200 W/(m*K).
