The behavior of composite material reinforced with carbon fibers under the effect of high-temperature gas flow

The regularities of high-temperature failure of carbon-filled plastics in a stream of chemically active gases are experimentally investigated at stagnation pressures of up to $30$ MPa and temperatures of up to $3000$ K. The obtained results correspond to the existing model of failure of heat-shielding materials in gas flows. It is shown that an intense heating of a composite polymer material may be accompanied by a time-constant cracking of its surface layer.
