The paper studies the mechanical properties of fabrics from Rusar threads in dry and wet condition, as well as the number of layers. The authors describe methods for determining the puncture resistance, cutting and punching, defined breaking load and elongation at break, resistance to puncturing, cutting and punching fabric from Rusar threads, when tested in one and several layers of dry and wet.

The possibility and technical efficiency of FA-513 nanomodifier application in the compositions of greasers No.76 and No.4C have been confirmed. Optimal concentrations of FA-513 for greasers in the manufacture of microplastics have been established by the impregnation method. The obtained microplastics showed an increase in physical and mechanical characteristics by 12-25%.

Developed and proposed technology for welding a saddle branch to a polyethylene pipe makes it possible to work at low ambient temperatures without constructing temporary heated shelters. Experimental welding took place in the natural conditions of the city of Yakutsk. Quality control by pull-off tests of the obtained welded joints showed the effectiveness of the developed technology for welding a saddle branch to a polyethylene pipe.
