Research Abstract

The developmental research on carbon-carbon composite materials with high thermal conductivity at high temperatures has been performed for the purpose of improving erosion properties at high temperatures as plasma facing component materials for fusion reactors. It was confirmed that the thermal conductivity of carbon materials increased due to heat treatment at higher temperatures than graphitization temperature and due to pressurized graphitization. Copper and silver which do not react with carbon at higher temperatures and have higher thermal conductivity were impregnated to fine-grained isotropic graphites (IG-430U and IG-43SU,non-impregnated IG-43) and a felt type carbon-carbon composite (CX-2002U) and six kind of composite materials have been produced on trial. As a result, the thermal conductivity of manufactured materials increased at higher temperatures as expectedly and the temperature dependence of thermal conductivity decreased. However, there was a material whose conductivity was smaller than that of the stating material. In order to improve it a small amount of titanium was impregnated to the composite materials (carbon/Cu/Ti) to make a better contact between carbon and copper. Consequently, the predicted results were obtained. It was made clear that the thermal conductive properties could be predicted from the mechanical properties by using the correlation of thermal conductivity with mechanical properties.
