COMPOSITE POLYMER ANTIFRICTION POLYAMIDE-BASED MATERIAL Russian patent published in 2015 - IPC C08J5/16 B82B3/00 C08L77/00 C08K3/04 

FIELD: chemistry.

SUBSTANCE: composite polymer antifriction polyamide-based material contains, wt %: carbon fibre or mixture of carbon fibre with glass fibre - 9.7-42.4, carbon nanotubes in form of monolayered or multilayered with number of layers from 2 to 70 or inserted into each other rolled in tube graphite planes with number of layers from 2 to 70 - 0.05-0.55, polyamide base - the remaining part. Outer diameter of nanotubes is selected from 0.1 to 100 nm, length - from 1 to 70 mcm. Polyamide base contains polyamide or mixture of polyamide with 20-40 wt % of poly-ε-capromide.

EFFECT: invention makes it possible to increase service term of products due to considerable reduction of intensity of linear wear during friction, increase stability of friction coefficient, increase destructing tensile stress, preserve Charpy toughness with preservation of specified compression strength.
