The object of the paper – is to improve abrasion resistance of capron-based awning material. The objectives of the present research are the following: to investigate the impact of polymer compounds, on the base of urethane thermoplastic material UK-1 structured by A-grade polyisocyanate, on the base of Z-grade chlorosulfonated polyethylene containing vulcanizing agents, stabilizers and pigment groups, on abrasion resistance of awning material with the pressure base of capron fabric. Research methods: test samples have undergone the complex of laboratory experiments for alteration of parameters of physical and mechanical properties before and after accelerated heat-and-light ageing in the STS apparatus. Abrasion tests have been carried out on the PIT-2 apparatus. Instrument measurements of physical and mechanical properties as well as visual evaluation of protective polymer coatings’ state have been taken as control parameters of abrasion resistance. Results obtained: the investigation has shown that abrasion resistance of soft barriers of awning structures and, correspondingly, their service life could be increased essentially by means of applying an additional layer of protective screen coating and its intermittent resurfacing adjusted for wear while in service. Re-surfacing intermittence should be done every 2 years provided the coating thickness of 100 micrometers.
