MATHEMATICAL MODELING OF PHYSICAL AND CHEMICAL EFFECT OF THE SUBLIMATION TAKING PLACE ON THE SURFACE OF A THERMAL PROTECTION COATING MADE OF POLYMERIC COMPOSITE MATERIALS UNDER INTENSIVE HEATING WITH HIGH TEMPERATURES
The behavior of physical-chemical processes proceeding on the thermal protection's surface made of the composite material at increasing temperature is examined. A mathematical model of physical-chemical transformations on the surface of thermal protection of fiberglass on phenol-formaldehyde resin made in the form of dependence of heat which taken by the thermo-destruction process under the high temperatures is proposed. This model takes into account the going of physical-chemical processes in the materials intended for heat protection and this model also allows calculating the amount of heat required for a thermo-destruction.
