▎ 摘　　要

The atomic structure of energetically stable composites based on carbon nanotubes and graphene has been studied. The energy stability has been determined from the change in the total energy of the studied system. It has been found that the geometric parameters of the nanotube affect the stability of the minimum structural link of the composite. The structural configuration of the composite with armchair nanotubes 12.12 in diameter and 18.44 in length exhibits the highest stability. It has been shown that the energy stability of the composite increases with an increase in the number of links in it.
