The Fast Manufacturing Process of 4 Directional Reinforced Carbon-Carbon Composites for Plasma Facing Component

摘要

Carbon fiber reinforced carbon (CFRC) composites have been used for several decadesin fusion power reactors. The major process studied for the CFRC was thermal gradientchemical vapor infiltration (TGCVI), followed by pressurized impregnation andcarbonization (PIC) process. After TGCVI, the density of carbon preform was increasedfrom 0.50g/cc to 1.70g/cc with uniform density profile along with the height and the radialdirection. By additional treatment of PIC process at the pressure of 10Mpa and a heattreatment to 2,400C in three times, the density of specimen was increased up to ~1.85g/cc.This result is comparable with that of high-pressure PIC at 100Mpa in five times.
