Comparative study of epoxy resins of different manufacturers

A comparative evaluation of a number of physical and mechanical properties (tensile and compressive strength, deformation capacity, heat resistance, adhesive strength, impact resistance, and abrasion resistance) of cured composites based on six resins of diff erent manufacturers on the domestic market was made. For the fi rst time, a comprehensive study of a number of important physical and mechanical properties of composites based on epoxy resins from Russian and major foreign manufacturing companies on the domestic market was carried out, which made it possible to formulate recommendations for their application in practice. The recommendations on the choice of epoxy resin for the manufacture of a polymer composite, taking into account the specific operating conditions of the product made with its use, are formulated.
