METHOD OF PRODUCING ANTIFRICTION METAL-BASED POLYMERIC ARTICLES Russian patent published in 2002 - IPC

FIELD: metal-based polymers and articles. SUBSTANCE: proposed invention can be used in making heavy-load sliding bearings. Proposed method comes to application of woven casing which consists of outer layer of threads made of polytetrafluoroethylene interwoven with inner layer of high strength organic fibers. Woven casing is preliminarily impregnated with thermoreactive binder consisting of resin part of product of interaction of epoxy 4,4′-isopropylidendiphenol resin, benzguamine, ε- caprolactam and novolac (soluble phenol-formaldehyde resins) hardened by aromatic amine. Prepreg thus formed is applied to heated metal surface at temperature from 80 to 200 C. EFFECT: provision of antifriction metal- based polymeric article with high thermal stability of antifriction layer. 3 cl, 2 tbl
