Change of the Wear Resistance of a Superhigh-Molecular-Weight Polyethylene Plate upon Its Modification by a Mechanically Activated Ceramic Nanopowder

摘要

The object of investigation is superhigh-molecular-weght polyethylene (SMWP) with a molecular weight of up to 8 × 10~6 g/mole and a particle size from 63 to 315 μm obtained by the technique developed at the Boreskov Institute of Catalysis, Siberian Branch, Russian Academy of Sciences. The purpose of this work is to create structural polymer materials with high physical and technical characteristics and to extend the scope of the application of this polymer in industry. The problem is solved by the modification of SMWP powder particles via the introduction of nanodispersed ceramic materials. Based on the data obtained, the methods of the production of the article samples from nanocomposite materials based on SMWP via the hot-pressing technique were developed and the influence of the nanomodifiers on the properties of the composite material was studied.
