Abstract

Tribotechnical properties of aromatic polyamides named poly para phenylene isophthalamide and polysulfonamide had been studied. It had been founded the optimal value of load and velocity for friction pair aromatic polyamide-steel while the grinding process of it. The influence of loadings and velocities on the main tribotechnical parameters of investigated friction pairs had been studied. It had been founded maximum value of load and velocity, which a friction pair aromatic polyamide-steel work in normal friction mode. It had been studied the physical-mechanical and thermal properties of aromatic polyamide. It was found, that accordingly to the level of strength characteristics aromatic polyamide is close to metals and their alloys. Thermal properties of investigated materials have a higher level than in other large-capacity polymers.
