Development of the Carbon Fiber Reinforced Carbon-carbon Composite for High Temperature Gas-cooled Reactors
In the present paper. details of the development of the candidate CIC composite are described. In the material development, especially, feasibility of the production. stableness of the supply and cost are much taken into consideration. As the physical properties of the material, high mechanical strength such as tensile and bending, high fracture strain and fracture toughness and low dimensional change by neutron irradiation have to be met. The developed 2D-C/C composite consists of plain-weave PAN-based carbon fiber cloth and pitch derived matrix. Also. high purification up to the level of nuclear grade was successfully attained in the composite.
