METHOD FOR OBTAINING CARBON FIBRE AND MATERIALS ON ITS BASIS Russian patent published in 2010 - IPC D01F9/16 D06M13/513 D06M15/643 D01F9/12

Abstract RU 2384657 C2

FIELD: textile, paper.

SUBSTANCE: invention refers to the method of obtaining carbon fibres from basic cellulose fibrous materials and can be used as reinforcing fillers of composite materials. The above method in a continuous mode involves three production stages: pre-carbonisation, carbonisation and graphitisation. At pre-carbonisation stage, basic cellulose fibrous material is saturated with liquid oligomeric resin solution with high content of silanol groups of common formula HO{[MeSi(OH)O][Me₂SiO]_m}_nH, where Me - methyl, m=1-3, n=3-10, with molar weight 900-2400, viscosity 520-1700 CP. Alcohols - derivatives of hydrocarbon family C₂-C₅and acetone represent an organic solvent.

EFFECT: invention provides formation of carbon fibres and fibrous materials having high strength properties.
