| Abstract. | Problem statement. As studies in the field of external reinforcement systems show, a change in the elastic modulus of adhesives used in reinforcement has an effect on the stressed-strained state of reinforced structures. The purpose of this work is to regulate and predict changes in the elastic modulus of epoxy adhesives. The objectives of the research are: the development of dispersed-filled epoxy compounds with various elasticity modules, conducting strength and creep tests and studying predictive models for predicting the modulus of elasticity of dispersed-filled epoxy polymers. Results. Epoxy compounds with different elastic modules have been developed and their physical and mechanical characteristics have been determined. The analysis of models for predicting the elastic modulus of epoxy polymers has been carried out, and good convergence of analytical models with experimental data has been revealed. Conclusions. The significance of the results obtained for the construction industry consists in identifying the operating range for predictive models depending on the content of the dispersed filler. This will allow you to pre-simulate the physical and mechanical properties of adhesives when developing them with predefined characteristics. |
