The prospective of the application of new materials on a polymer base is shown in this work. Given that developed composites can be efficiently used for protection of equipment that is operated at elevated temperatures, the impact of the nature and content of powder mixture, synthesised by high voltage electric discharge, on the thermophysical properties of epoxy composites were studied. Epoxy diane oligomer was chosen as the main component of the binder during the formation of the composites. Polyethylene polyamine hardener was used for cross-linking of epoxy composites, which allows hardening of materials at room temperatures. The selection of powder mixture, synthesised by high voltage electric discharge, for increase of thermophysical properties of developed materials was justified. More so, thermal stability and activation energy of epoxy composites were studied. Permissible limits of the temperature, at which developed materials can be used, were established based on the conducted tests of thermophysical properties of materials, filled by powder mixture, synthesised by high voltage electric discharge.
