Graphites and/or C/C-composites as plasma-facing first wall components for fusion reactor devices are so severely subjected to plasma disruption. Therefore the thermal shock resistance and fracture toughness of these materials must be evaluated whether or not they have appropriate performances. In this paper, the thermal shock resistance and fracture toughness of several kinds of graphites and C/C-composites for candidate first wall component tiles ere determined by means of arc discharge heating for disk specimens. The mechanical and fracture mechanics properties of these specimens are also measured. Two graphites and three C/C-composites are irradiated up to 1.9×1021n/cmcm2 (E>29fJ) at 650-1, 000°C in a fission reactor (Japan Material Testing Reactor; JMTR) and the degradations in the thermal shock resistance and fracture toughness and the changes of mechanical and fracture mechanics properties due to neutron irradiation are quantitatively given. |
