The results are given of experimental investigations of basic regulari
ties of hyperthermal destruction of typical structural epoxy glass on
interaction with gas flows under high pressures (up to 15 MPa). A phys
ical model of the process under study is formulated. The modes of ther
mochemical and thermomechanical destruction, melting, flow of film, an
d shear deformations (erosion) of a thin surface layer of epoxy glass
heated to high temperatures are identified.
