The influence of the nature of modifiers of different natures on the properties of epoxy resin is investigated. The influence of modifiers, in particular starch, epoxidized soybean oil, and polyvinyl butyral, on the physical and mechanical properties of epoxy composites is determined. The influence of the nature of the modifier on the thermophysical properties of modified epoxy resins is determined. It is found that both chemical and physical processes in the component system have a significant influence on the nature of thermomechanical dependencies.
