THERMOCHEMICAL DESTRUCTION OF A CARBON-EPOXY COMPOSITE UNDER MULTIPLE-PULSE LOADING

The process of nonstationary heat and mass transfer in a composite mat erial during. radiative-convective heating is analyzed numerically wit hin the framework of a thermal model of destruction of the reacting me dium. The different regimes have been established for thermochemical d estruction and combustion of a carbon epoxy composite under the action of laser radiation of moderate intensity. It has been found that in s hielding the laser radiation by the products of material destruction a decisive role is played by the gaseous products of pyrolysis, particl es of the condensed phase, and vapors of the carbon component.
