The presented article presents the results of investigations of operational characteristics and thermal stability of polymer composites whose matrix is represented by epoxy resins modified with different kinds of inhibiting fillers. An analytical literature review has been performed, methods and methods of obtaining flame retardant composites have been studied. Experimental study of the influence of inhibiting modifiers - fine fillers: iron oxide, silica flour, graphite, talcum, copper oxide has been carried out. According to the results of the experimental study, the modification of the epoxy matrix of the composite by the introduction of inhibiting fillers by ultrasonic treatment contributes to an increase in thermal stability. The modified material is characterized by decrease of intensity of destruction of the material matrix, expressed in decrease of mass loss level, decrease of maximum value of thermal effect, increase of oxidation period, and also steady formation of a thermal insulating carbonaceous layer.
