Abstract

In the study the technological and operational characteristics of the epoxy resin system VSE-81, developed at the NRC «Kurchatov Institute» – VIAM, are considered. The results of gelation and rheological tests are presented. Mechanical properties are obtained by stretching VSE-81 samples cured according to the selected mode, and the conversion rate is determined by the DSC method. We compared the mechanical characteristics of microplastics based on UMT49S-12K-EP carbon fiber with VSE-81 binder and its imported analogue. The results of microstructural research interpreted using a model of the microcomposite structure of thermosetting polymers are presented.
