FIELD: machine engineering. ^ SUBSTANCE: invention relates to material used in making tribotechnical articles exploited without using lubricant and under effect of increased temperatures. Material comprises the following components, wt.-%: dry lubricant, 1-5; carbon-containing filling agent, 1-40, and polytetrafluoroethylene, the balance, up to 100. As a carbon-containing filling agent the following dispersed particles of thermoplastic polymers are used taken among the group comprising polyamides, polyolefins, polysulfone, polyacrylonitrile or their mixtures in the ratio of size of maximal section of filling agent particle to size of polytetrafluoroethylene particle = 0.1-1.5. ^ EFFECT: enhanced strength and abrasion resistance. ^ 2 tbl |
