This paper presents the results of a numerical evaluation of the thermal conductivity of a graphene-nanotube film composite with vertical packing of nanotubes between graphene layers. Various topological models of composites are considered. These models are differing in the diameter of nanotubes and the distance between them in the composite. It is shown that the heat-conducting properties of a graphene-nanotube composite are determined mainly by the thermal conductivity of the carbon nanotubes entering into its composition. A method for controlling the thermal conductivity of graphene-nanotubular structures of the considered type is revealed on the basis of the obtained results.
