Abstract
The results of studies of changes in the physical and mechanical properties of heat-resistant polyethylene terephthalate (PET), polymide (PI) and fluoroplastic (PP) films, as well as synthetic polyethylene terephthalate (PET) and aramid fabrics in a wide range of specified exposure temperatures and temperature exposure times are presented. The most suitable heat-resistant polymer films and fabrics for use in inflatable structures of aeronautical equipment have been identified. An assessment of the operational parameters of the investigated materials showed linear character of change in properties in a given temperature and time interval of researches.
