- Аннотация: The results of studying of the physical-mechanical properties of DGEBA-epoxy resin cured by 4,4'-diaminodiphenylmethane (DDM) are presented. The molar ratio of the concentrations of amine (NH) and epoxy (EP) groups are: 0.5; 0.6; 0.7; 0.75; 0.8; 0.9; 1; 1.11; 1.25; 1.33; 1.43; 1.66; 2. Samples of the cured resin were examined in tension and three-point bending according to ASTM D638-10 and ASTM D 3039 standards, respectively, using the Zwick / Roel TC-FR010 universal testing machine. As a result, the dependencies of the resins physical-mechanical properties (modulus of elasticity, strength, elongation at break, glass temperature) on the NH / EP ratio and the curing temperature were obtained.
