Title:
BORON CARBIDE/CARBON FIBER COMPOSITE SINTERED COMPACT FOR WALL MATERIAL OF NUCLEAR FUSION REACTOR
Document Type and Number:
Japanese Patent JPH0687672
Kind Code:
A
Abstract:
PURPOSE: To obtain a wall material for a nuclear fusion reactor having remarkably improved heat conductivity and thermal shock resistance without losing the conventional characteristics by combining boron carbide with carbon fibers in a specified ratio and sintering them.
CONSTITUTION: This composite sintered compact for the wall material of a nuclear fusion reactor consists of 90-50vol.% boron carbide and 10-50vol.% carbon fibers. In this composite sintered compact, the carbon fibers are preferably oriented so that the angle between the fibers and the direction of heat conduction is regulated to ≤±30°. The aspect ratio of the carbon fibers is preferably ≥100.
