Abstract
The paper explores the curing processes of unfilled epoxy resins ED-16. Mathematical modeling of curing processes has been performed and mathematical models of curing processes are presented in the form of full quadratic polynomial models. Separately, the degree of curing of unfilled epoxy compositions is studied. As a result of exploring the obtained models and performing optimization procedures for the ED-16 resin, theoretical aspects of curing high-viscosity epoxy systems were developed and recipe-technological parameters for obtaining a high-strength polymer matrix based on the high-viscosity ED-16 resin were proposed, which makes it possible to obtain epoxy composites with specified parameters structures and properties.
