With the aid of a complex experimental procedure, 
we consider the mechanism of thermal destruction of carbon-phenol 
thermal protective compositions with a different content of components 
in the interaction with a high-enthalpy gas flow. Thermophysical, 
thermokinetic, and structural properties of the thermal protective 
compositions are determined. The effect of the rate of heating on 
characteristics of the transfer coefficients, which is specified by 
a kinetic shift of the pyrolysis reactions to a high-temperature region, 
is ascertained.
