摘要 |
A densified carbon matrix carbon fiber composite preform is made by vacuum molding an aqueous slurry of carbon fibers and carbonizable organic powder to form a molded part. The molded part is dried in an oven at 50 DEG C. for 14 hours and hot pressed at 2000 psi at 400 DEG C. for 3 hours. The hot pressed part is carbonized at 650 DEG C. under nitrogen for 3 hours and graphitized at 2400 DEG C. to form a graphitic structure in the matrix of the densified carbon matrix carbon fiber composite preform. The densified preform has a density greater than 1.1 g/cc. |
