FIELD: antifriction materials. SUBSTANCE: invention describes a new antifriction composition material consisting of phenolic resin, graphite and synthetic fiber. It has polyoxadiazole or poly-para-phenylene- terephthalamide, or polyamidobenzimidazole fiber as synthetic fiber, phenolformaldehyde or cresolformaldehyde resin as phenolic resin and cotton fiber additionally and aluminium oxide also at the following ratio of components, wt.-%: polyoxadiazole or poly-para-phenyleneterephthalamide, or polyamidobenzimidazole fiber 25-57; phenolformaldehyde or cresolformaldehyde resin 18-43; graphite 1.5-16; cotton fiber 6-42 and aluminium oxide 0.3-9. The proposed antifriction composition material exhibits low friction coefficient, high resistance to stratification at simultaneous retention of low wear of necessary strength and impact viscosity. EFFECT: improved quality and properties of the composition. 2 cl, 2 tbl |
