INFLUENCE OF MODIFIED EPOXY RESIN ON PHYSICAL AND MECHANICAL PROPERTIES OF EPOXY COMPOSITE

The main physical-mechanical and thermophysical characteristics of composite materials based on epoxy resin ED-20 and peroxide resin ED-20P (modified with tert-butyl hydroperoxide ED-20 of a molecular weight 480) in the ratio of 30 mass parts of ED-20P to 70 mass parts of ED-20 and unsaturated oligoester TGM-3 were researched. Butyl methacrylate was used as the active diluent of epoxy-oligoester mixtures. The polyethylene polyamine was used as hardener in a steochemical ratio. For the comparison we studied compositions which did not contain ED-20P resin.
