Abstract

Aim. We determine the relationship between the parameters of a materials structure and metrics of their thermal protection properties. Methodology. Use is made of a theoretical analysis and comparison of theory and experiment based on the results of two methods of practical measurements of the thermal conductivity components of a random scattering medium. Results. A method for measuring the radiant, conductive and total heat transfer coefficient of the medium using screens is described. A new method for determining the components of heat transfer with use the compression of the canvas is found. Metrics of heat-shielding properties of materials are measured. Research implications. It is found that the conductive component of the thermal conductivity of light insulation materials is almost equal to the thermal conductivity of air, and the radiant component is inversely proportional to the density of the structure. The conductive and radiation parameters of the medium are determined.
