PRODUCTION OF CARBON/CARBON COMPOSITE MATERIAL USING CARBON/CARBON COMPOSITE ROD

摘要

PURPOSE:To obtain a carbon/carbon composite material having excellent strength and toughness by compactly packing a carbonaceous substance in the space of preform formed by a carbon/carbon composite rod filling the carbonaceous substance in the space of a carbon fiber bundle. CONSTITUTION:A precursor of carbon is impregnated into the space of carbon fiber 14 bundle and then burned or a carbonaceous substance 15 is filled into the above-mentioned space by a vapor phase method to remove residual pores. Carbon/carbon composite rod 12 obtained by the first process is oriented into two dimensions or tree dimensions to form a preform 13 of fabric, etc. The above-mentioned precursor is impregnated into the space distributing in the two dimensions or three dimensions in the preform 13 obtained by the second process and then burned or compounded by vapor phase method or in combination thereof to provide the carbon/carbon composite.
