A rheological mathematical model that describes the process of formation of internal heat sources in a polymer composite material during its force loading, based on the process of microdestruction formation and the formation of dynamic temperature fields on the surface of the structure during thermal control, has been developed. The methodology as well as software and hardware for computer thermal control and diagnostics of the technical condition of complex spatial structures from PCM based on recording information about dynamic temperature fields have been developed and implemented. A thermal method has been developed for the quality control of composite armored barriers made of aramid materials through the study of the processes of its interaction in real time with a damaging element (kinematic, deformation, wave, thermal processes), which allows to increase the reliability of the quality of diagnostics, increase testing efficiency, visibility and objectivity of the results.
