IMPREGNATED YARNS OF GLASS FIBERS AND CLOTH ON THEIR BASE Russian patent published in 2003 - IPC

FIELD: fiber yarns with coating. SUBSTANCE: yarns of fibers with coating include, at least, one fiber having layer of dried residue compatible with polymers of coating composition, at least, on a part of surface, at least, of one fiber. Coating composition compatible with polymers includes: (a) multitude of discrete and stable in size particles produced from materials selected from group consisting of organic materials, polymer materials, composite materials and their mixtures ensuring production of hollows between one fiber and, at least, one adjacent fiber, with particles having overage size of about 0.1 to about 5 mcm; (b) at least, one lubricating material; (c) at least, one polymer film-forming material, and (d) at least, one finishing agent. Invention also covers cloth including, at least, one of such yarns of fibers. EFFECT: reduced wear and brittleness of fibers in friction, provided good wettability and impregnability of coating with matrix material. 59 cl, 8 dwg, 5 tbl, 4 ex
