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.
The results of research on the thermal stability of epoxy resins modified with carbon nanomaterial as polymer composites matrices are presented. It is shown that modification of binder component of composite materials at deposition of carbon nanomaterials leads to improvement of thermal stability, including decrease of intensity of crystal lattice destruction, decrease of amplitude value of thermal effect, increase of duration of oxidation of material at high temperatures, promotes stable formation of heat-protective and insulating carbonized layer.
An analysis was made of the current requirements for the training of fire and technical experts and external pilots of the emergency and disaster response system. By the example of training forensic experts of forensic institutions and expert subdivisions of the Federal Fire-Fighting Service of the State Fire-Fighting Service (fire extinguisher expert) the introduction of new professional standards into the educational system of this specialty was examined, on the basis of which the recommendations for modifying the educational program, in order to increase the quality of fire place examination were proposed. When extending the training program of the firefighting expert in the field of external piloting training, the trainee will additionally master professional competences in control and maintenance of unmanned aerial systems. Supplementing the training program for specialists of judicial-expert and expert subdivisions of the Federal Fire-Fighting Service of the State Fire-Fighting Service with labor functions in flight operation of unmanned aircraft systems, including one or more unmanned aircrafts, will allow the graduate of the educational organization to be awarded the qualification “External pilot”, which, in turn, will also improve the quality of the above-mentioned subdivisions.
