GLASS THREAD COVERED WITH OILING COMPOUND; OILING COMPOUND; METHOD FOR PRODUCING OILED GLASS THREADS AND COMPOSITE BASED ON MENTIONED GLASS THREADS Russian patent published in 2002 - IPC

FIELD: production of oiled glass threads and composite parts from them. SUBSTANCE: oiling compound for glass threads is formed by solution of viscosity lower than or equal to 400 cP including less than 5 mass percent of solvent and incorporating at least one thermally polymerized base system; mentioned base system has at least 60 mass percent of components whose molecular mass is below 750 and at least 60 mass percent of component (components) mixed up with at least one reactive epoxy group and component (components) with at least one reactive anhydride group. Compound may include catalyst, crosslinking agent, film-forming agent, and textile agent. Oiled glass threads are produced using this compound prepared by this method. Glass threads produced in this way are well compatible with various materials used for manufacturing composite parts. EFFECT: enhanced flexibility, integrity and effective shielding of threads against abrasive wear. 13 cl, 2 tbl, 14 ex
