GLASS FIBRE AND COMPOSITE MATERIALS WITH ORGANIC AND/OR INORGANIC MATRIX, CONTAINING THEREOF Russian patent published in 2013 - IPC C03C13/00 

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: SiO₂ 57-65%, Al₂O₃ 15-23%, SiO₂ + Al₂O₃ >79%, CaO 1-10%, MgO 6-12%, Li₂O 1-3%, preferably 1-2%, BaO+SrO 0-3%, B₂O₃ 0-3%, TiO₂ 0-3%, Na₂O+K₂O <2%, F₂ 0-1%, Fe₂O₃ <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.
