ANTIFRICTION COMPOSITE MATERIAL AND METHOD OF ITS PRODUCTION Russian patent published in 2025 - IPC C08J5/16 C08L61/16 C08K3/04 C08K3/10 

FIELD: chemistry.

SUBSTANCE: invention relates to composite materials based on polyarylether ketones and can be used in any industry for production of parts for tribotechnical purposes, in particular hydrodynamic plain thrust bearings of axial supports of pumps and electric motors of submersible well centrifugal and screw pump units for oil production. Method of producing antifriction composite material includes the following steps: mixing powdered polyarylether ketone, polytetrafluoroethylene, carbon fibre and copper by dispersing a suspension of components in ethyl alcohol with ultrasonic treatment for 3-5 minutes; hot pressing at pressure 10-25 MPa and temperature 350-450 °C with subsequent cooling rate of 2-3 °C/min.

EFFECT: disclosed approach enables to obtain an antifriction composite material with low friction coefficient and high thermal conductivity index/coefficient for tribological parts.
