COMPOSITE MATERIAL Russian patent published in 2005 - IPC

FIELD: aircraft industry; space industry; electrical industry; motor car industry; instrument-making industry.

SUBSTANCE: the invention is pertaining to the field of aircraft engineering, space engineering, electrical technology, motor car and instrumentation technologies, in particular, to composites produced on the base of glass dies reinforced by continuous carbon filling materials. The technical result of the invention ensures an increased heat-resistance of a composite material at operational temperatures above 800°C. The composite material includes (in mass %): a glass die - 60.5-73.5 and a high-modular carbon fibrous material - 26.5-39.5. The glass die contains ingredients in the following ratio (in mass %): SiO₂ - 58.9-87.4, B₂O₃ - 2.7-15, SiOC - 4.5-11.5, TiSi₂ - 4.5-11.5,_{SiB4 -0.9-3.7.}

EFFECT: the invention ensures an increased heat-resistance of a composite material at operational temperatures above 800°C.
