ABSTRACT

The development of energetics, machine building and chemical industry is not possible without chemically stable materials. Polytetrafluoroethylene (PTFE) is one of these materials. Composites on the basis of PTFE have very wide use in machine building as antifriction and friction elements.

Physical-mechanical and tribological properties of the composites on the basis of PTFE with conductive (graphite) and insulator (andesite) fillers have been investigated in the presented work. The advantage of binary filler in comparison to monofiller (graphite) is shown.
