Abstract: Measurement data on unsteady temperature fields in decomposing thermoprotective coatings and on mass losses in a high-temperature inert-gas (nitrogen) flow are reported. With the use of analytical and numerical methods for solving boundary and coefficient inverse heat- and mass-transfer problems, thermophysical and kinetic characteristics of thermoprotective materials made by two modifications of chlorosulfonated polyethylene and powdered polypropylene filler are found.

Keywords: thermoprotective coating, composite material, heating, temperature field, thermophysical characteristics, thermodestruction, kinetics, inverse problems.
