Effect of liquid-phase filler on triboengineering properties of PTFE-based composites

The work presents the results of investigation of developed polytetrafluoroethylene-based wear-resistant polymer composites filled with the liquid-phase mineral motor oil. The technology for manufacture of a microporous fluoroplast whose pores are filled by a liquid motor oil under different temperatures is described. The developed technology forms the basis of the development of oil-filled triboengineering polymeric materials with elevated wear resistance. It is found that sorptive permeation of the liquid lubricating material into the polymer binder bulk intensifies with temperature and with the use of natural adsorbents. The triboengineering properties of polymeric materials containing a liquid lubricating material and natural adsorbents are studied. New materials with elevated wear-resistance and load-bearing parameters are developed for the friction joints of different purposes.
