FIELD: chemistry.SUBSTANCE: invention relates to glass fibres, intended for, in particular, obtaining composite materials with organic and/or inorganic matrix, in composition of which included are the following components in specified below ranges, expressed in weight percent: SiO57-65%, AlO15-23%, SiO+ AlO>79%, CaO 1-10%, MgO 6-12%, LiO 1-3%, preferably 1-2%, BaO+SrO 0-3%, BO0-3%, TiO0-3%, NaO+KO <2%, F0-1%, FeO<1%. Said fibres are formed from glass, offering excellent compromise between mechanic properties, expressed by specific Young's module, and conditions of melting and formation of fibres.EFFECT: increase of specific Young's module.12 cl, 1 tbl |
