Abstract

In order to develop antifriction extrudable composites with micro- and nanosize fillers the mechanical and tribotechnical characteristics of ones with a hybrid polymeric "UHMWPE + polytetrafluoroethylene (PTFE)" matrix under dry sliding friction were investigated. It is shown that the wear rate of micro- and nanocomposites based on the "UHMWPE + 10 wt.% PTFE" matrix under dry sliding friction is reduced by 10-30 %. Mechanical characteristics are not changed significantly in the nanocomposites, while in the microcomposites they are reduced substantially. By means of scanning electron microscopy, differential scanning calorimetry and optical microscopy the permolecular structure, degree of crystallinity and surface topography of micro- and nanocomposites based on the hybrid matrix were investigated. The mechanisms of wear of "UHMWPE-PTFE" composites under dry sliding friction are discussed.
