Specific features of thermochemical processes in high-temperature coke of polymer composite materials

The temperature fields in coked layers of polymer composite materials (fiberglass plastics) under high-temperature heating and subsequent cooling in a cold oxidizer flow are experimentally studied. Based on the analysis of experimental data and numerical research, it is shown that exothermal chemical reactions can proceed in the coked layer of fiberglass plastics, which creates conditions for maintaining high temperatures in the composite-coke layer during a rather long time.
