abstract

The article is devoted to the evaluation of the wear resistance of threaded seams of membrane materials on the knitted basis in the simulation of operation according to the criterion of reduction of strength indicators. As a result of the experiment, it has been detected that the breaking load of all the studied samples of thread seams practically does not change when the tensile strength increases in the range from 0 to 25 %, both along and across the seam. Absolute elongation of all specimens decreases with increasing percentage of specimen stretch when simulating operational loads, but it is not critical. Threaded seams of three-layer membrane materials on a knitted base made using the modes recommended in the article are characterized by stable strength and sufficient wear resistance.
