Abstract

The effect of various nanofillers (nanofibers of Al2O3 and carbon, nanopowders of copper and SiO2) on the physico-mechanical and tribotechnical properties of superhigh-molecular polyethylene is investigated. It is determined that the modification of superhigh-molecular polyethylene by nanofibers and nanoparticles within the limits of 0.1-05 wt % results in a substantial rise in its deformation-strength characteristics and a multifold increase in its tribotechnical characteristics. By the methods of X-ray structure analysis, infrared spectroscopy, and electron microscopy, it is shown that modification of the polymer by the mentioned nanofillers results in the formation of an ordered (lamellar) permolecular structure. It is revealed that nanofibers form a stable film of friction transfer more quickly in comparison with nanoparticles. The optimum compositions of nanofillers, which determine the high wear resistance and the low constant of friction for polymer, are determined. The mechanical activation of the binder and filler powders provides a uniform distribution of the nanopowder within the binder and additionally enhances the physico-mechanical and tribotechnical properties of the composite.
