Abstract

Computer simulation of the properties of Nanomodified Adhesive Compositions (NMC) based on ED-20 epoxide resin doped with carbon nanomaterials was carried out. It is shown that open carbon nanotubes are an efficient additive to increase mechanical shearing properties of adhesive compositions based on epoxide matrix. Using the nanoindentation method it was found that introduction of carbon nanotubes 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.
