Structures of the powdered polytetrafluoroethylene (PTFE) before and after intensive mechanical activation (mechanical alloying) are investigated by the set of physical research methods. Enhancement of physical and mechanical properties and structuring activity of polytetrafluoroethylene as matrix of composites by means of mechanical activation is shown. Operating modes of mechanical activation equipment are defined, in which the service properties of PTFE are maximized. The effect of mechanical activation technology on restructuring and change of morphology and supramolecular structure of PTFE is detected for the first time. Obtained results and examples of implementation of the developed tribotechnical composites are analyzed.
