FIELD: friction materials. ^ SUBSTANCE: invention relates to technology of preparing asbestos-free friction article for use in a variety of friction mechanisms (brake assemblies of motor cars and equipment). Friction article comprises 15% of polymeric binder, 6% of reinforcing component, 46% of powdered interaction filler, 32% of metal-containing filler, and, additionally, 1% of pulp composed of fibers degrading at temperature 130-250°C arising on working surface of friction article upon braking. Fibers are selected from group including cotton, cellulose, and viscose fibers. ^ EFFECT: improved performance characteristics of articles due to reduced probability of formation of gas and liquid phases on friction couple surfaces upon braking. ^ 1 tbl |
