PERSPECTIVE DIRECTION OF CALCULATION AND DESIGN OF REINFORCING CARCASSES OF TENSION FIRE HOSES ON BASIS OF SYNTHETIC FIBERS

The physical and chemical properties of synthetic fibers of various compositions for reinforcing carcasses of pressure fire fibers, and their appointment and structure were de-noted. It is noted that due to the effect of negative factors (mechanical wear, impact of low and high temperatures, the action of sunlight, aging of the material, accidental release of chemically active substances, etc..) on pressure fire hoses at their exploitation, increased de-mands are imposed on the material of synthetic fibers of pressure fire hoses, the most im-portant of which is resistant to abrasion. The use of pressure fire hoses from polyester fibers based on PET shows that the main reason for breaking up the fibers at their exploitation is abrasion of the surface.
