FIELD: mechanical engineering; manufacture of brake linings, clutch rings and other articles used in brake and friction mechanisms. SUBSTANCE: in proposed method of manufacture blank is made by winding of impregnated threads, article is formed from this blank and machined to required size and holes are made in article. In process of forming cavities are made in article with sizes corresponding to sizes of holes in article after mechanical machining. Distance from bottom of cavities to surface of article opposite to surface provided with cavities is either equal to or less than thickness of layer removed from surface of article opposite to surface with cavities at mechanical machining of article to required size.
