The results of experimental investigations of the porous 
structure of four glass-reinforced plastics after the interaction 
of them with high-temperature flows have been presented. The dependences 
of the accessible porosity on the thermal-action time have been obtained. 
The values of the initial porosity of the glass-reinforced plastics 
have been determined. The values of the effective radii of micro- 
and macropores at different times of high-temperature heating of the 
glass-reinforced plastics have been calculated.
