Abstract

The results of an investigation of the physicomechanical properties of foreign (D.E.R. 330) and domestic (KhT-711) epoxy matrices, including those modified with polysulfone or polyetherimide, are presented. It is shown that the glass-transition point of epoxy compositions based on KhT-711 resin cured with iso-MTHPA can reach 190°C and exceeds the glass-transition points of the foreign binders by 15–30°C. The elastic moduli of the compositions based on KhT-711 resin are higher than those of the matrices based on D.E.R. 330 by 40–60%. All the investigated epoxy matrices exhibit seemingly high resistance to the action of acids, alkali, oil products, and water, whereas KhT-711 + iso-MTHPA + heat-resistant thermoplastic demonstrate a five to six times lower mass loss than do foreign matrices.
