A study has been made of the influence of oxidizing media 
(an air medium and a steam<196>helium mixture) in heating on the structure 
and thermoooxidation stability of carbon-based fibrous materials with 
alumina, silica, and silicon-carbide coatings applied to the surface 
of the fibers. It has been established that determining factors in 
production of protective films are the adhesive interaction of the 
reagents with the fiber surface and the regime of their heat treatment. 
It has been shown that the protective films formed increase the thermooxidation 
stability of carbon-based fibrous materials 1.5<196>2 times.
