AbstractAbout the AuthorReferences
Results of the study of physical-mechanical characteristics of modified epoxy glues for the systems of external reinforcement of building structures are presented. It is established that the introduction of multi-layered carbon nanotubes within the range of 0.001–0.025 pts.wt. per 100 pts.wt. of the epoxy resin leads to a slight increase in strength and modulus of elasticity when compressing the cured compound. At this, the nano-modification leads to a significant increase in adhesion characteristics of compositions: shear strength (to steel) and tensile uniform strength (to steel and concrete) increase by 40% and more within the range of optimal concentrations of nano-particles. The nano-modification makes it possible to increase the modulus of elasticity of carbon fiber reinforced plastics produced on the basis of carbon fabric and glued binder when preserving the high tensile strength.
