Electronic-microscopic researches show the change of supramolecular structure with formation of well-organized structures at introduction carbon nano particles in epoxy binder on the basis of epoxy resin of ED-20 and isomethyl tetrahydrohthalic anhydride was chosen as a hardening agent. Possibility and effectiveness of use of ultrasonic dispersion of super concentrate on basis of CNT in the composition of resin was analyzed. Research of influence of CNT concentration from 0 to 0,5 mass% in the composition of epoxy resin on the tensile strength and module of elasticity at stress and compression, Charpy impact strength is carried out. It was established that when introducing CNT into the composition of epoxy resin changes of elastic- strength properties are on served. It was experimentally determined that modification by means of super concentrate on basis of CNT results in increase of tensile strength and module of elasticity at stress and compression, Charpy impact strength. At CNT concentration in the epoxy resin composition from 0,25 mass% to 0,5 mass% increase of tensile strength at stress on 32% and module of elasticity at compression on 10% is observed. © 2020 The Authors.
