Modern development of scientific and technics are complicated without usage of heat-resistance polymeric composites with high level of physical-mechanical properties. For their creation it is necessary to combine an initial thermostable polymeric matrix with fillers of various nature and morphology. 
It is known [1-3] that usage of disperse nano-sized fillers allow to increase the level of heat-resistance and physic-mechanical properties of polymeric composites.
We had been created polymeric composites based on aromatic polyamides, fluoroplastics, phenolic resins and nano-sized silica [4,5].
The optimal parameters of processing created PC in products were selected. The investigations of thermophysical, physical-mechanical and tribotechnical properties of created PC were conducted. It is established that products from the developed materials can work at temperatures to 300oC and loadings to 260 MPa in constructional and tribotechnical unit of machines and mechanisms that work in severe conduction with and without oiling.
