Computer simulation of the properties of Nano-modified Adhesive Compositions (NMC) based on ED-20 epoxide resin doped with carbon nano-materials was carried out. It is shown that open carbon nano-tubes are an efficient additive to increase mechanical shearing properties of adhesive compositions based on epoxide matrix. Using the nano-indentation method it was found that introduction of carbon nano-tubes into adhesive compositions results in increasing their elastic behavior by 20–25%. It was shown by experiments that NMC application in bolted connections leads to increase of the bonding strength by 18% and fatigue life at least fourfold.
