FIELD: technological processes.
SUBSTANCE: invention relates to the field of material science, in particular, to anti-friction polymer composite materials, and may be used in manufacturing of parts of metal-polymer friction units and in general machines of various types of equipment. The method to manufacture items from polymer composite materials on the basis of polytetrafluorethylene consists in the fact that fillers are mixed with polytetrafluorethylene in a mixer with rotation frequency of 2800 min-1, and cold pressing is carried out in a closed die mould. Then the pressed stock is installed into the closed device, and additional pressure of compression is developed in the pressing direction. Besides, the additional pressure of compression is regulated and set within 2.0 - 8.0 MPa.
EFFECT: increased characteristics of mechanical and tribotechnical properties of a composite material based on polytetrafluorethylene.
