FIELD: polymer materials. ^ SUBSTANCE: invention relates to polymeric composite materials for various-destination friction articles. Composition of invention contains, wt %: powderlike binder (SFP-012 and AK-30), which is mixture of novolac phenol-formaldehyde binder and nitrile rubber obtained via joint coagulation of their latexes, 15-18; barite concentrate 30-40; alumina 10-15; bronze chippings 3-5; graphite 3-5; non-stoichiometric titanium compound 2-5; and polyoxadiazole fiber (Oksalon) or mixture thereof with glass fiber at ratio 1:2 - the balance. ^ EFFECT: enhanced adhesion strength of material to metallic framework, increased friction coefficient, and reduced high-temperature wear and price of material. ^ 3 tbl, 4 ex |
