Abstract
Epoxy composite materials (ECMs) and composite protective coatings are important for the improvement and further development of many engineering areas. Owing to the combination of components with different physical, chemical, thermal, and mechanical properties, ECMs have unique adhesive strength, wear resistance, heat resistance, and corrosion resistance. To obtain ECMs, ED-20 epoxy resin, polyethylene polyamine as a curing agent, modifiers, and multifunctional reinforcements are used. Methods to control the structure and properties of ECMs with different reinforcement contents are justified and structurization mechanisms depending on the nature and morphological features of the ingredients and their ratio in the system are established in comprehensive research. The rheological properties of epoxy composites depending on the reinforcement content are analyzed. The classification of epoxy composites into low-reinforced, medium-reinforced, and high-reinforced systems is shown to be reasonable. Predominant factors that influence the properties of relevant materials are identified.
