COMPOSITE MATERIAL AND DEVICE MADE FROM THIS MATERIAL Russian patent published in 2007 - IPC C04B35/80 C03C14/00 

FIELD: composite materials on base of glass matrices reinforced with carbon fibrous fillers for manufacture of heavily loaded parts, tread rings, for example; aeronautical, space and mechanical engineering.

SUBSTANCE: proposed composite material is intended for operation at working temperatures up to 800C. Proposed composite material includes glass matrix containing SiO₂, B₂O₃ and carbon fibrous filler whose glass matrix contains additionally Al₂O₃, SrO, BaO, TiO₂ at the following ratio of components, mass-%: glass matrix, 60.5-73.5; carbon fibrous filler, 26.5-39.5 at the following ratio of components of glass matrix, mass-%: SiO₂, 35.0-55.5; B₂O₃, 6.0-15.0; Al₂O₃,12.0-15.0; SrO, 9.0-10.0; BaO, 12.0-15.0; TiO₂, 5.5-10.0. Carbon fibrous filler is made in form of thread, tape, cloth or cord.

EFFECT: enhanced heat resistance of composite material.
