It is shown that the oxidized carbon nanotube adsorbs the triethylenetetramine molecule on its surface precisely by amino groups, which are reaction centers during its reaction with the original resin. Thus, the oxidized surface of the nanotube worsens the interaction of the hardener with the epoxy resin during the formation of a three-dimensional polymer lattice of the finished nanocomposite, which is confirmed by experimental data. A brief description of methods of obtaining nanofillers of composite materials: carbon nanotubes, thermally expanded graphite, graphene nanoparticles, composite filler carbon nanotubes - graphene nanoparticles, their characteristics is given. It is shown that for viscous substances such as epoxy resins, mixing on a three-roll mill is an effective method of filler introduction. The vacuum infusion method is cheap and effective for the production of fiberglass reinforced with nano-sized carbon fillers. The technology of reinforcing the layered composite material of the UAV body using modified forms of carbon nanotubes has been developed, which gives a synergistic effect of increasing the strength characteristics. It was implemented at OJSC "Meridian" named after S.P. Korolyova (A new model of the "SPECTATOR" UAV was created, model M 1, which uses created composites from VNT, which have improved properties).
