PRODUCTION METHOD OF CARBON FIBER REINFORCED CARBON COMPOSITE MATERIAL COATED WITH THERMAL DECOMPOSITION CARBON

摘要

PROBLEM TO BE SOLVED: To provide a production method which achieves low-cost production of carbon fiber reinforced carbon composite material coated with thermal decomposition carbon which has excellent corrosion resistance and gas-sealing property.;SOLUTION: This production method of carbon fiber reinforced carbon composite material coated with thermal decomposition carbon features that carbon fiber reinforced carbon composite material is impregnated with resin or pitch which turns to optically isotropic carbon by burning, is cured or is made infusible and is burned and, thereafter, hydrocarbon gas is flown as raw material gas and hydrogen gas is flown as carrier gas thereinto and the carbon fiber reinforced carbon composition material is coated with thermal decomposition carbon at a temperature of 1200-2000°C under the reduced pressure.;COPYRIGHT: (C)2003,JPO
