| Abstract Scope |
Reduced activation ferritic/martensitic (RAFM) steel is one of the primary candidates for blanket modules in a nuclear fusion reactor. Increasing the thermal conductivity of the blanket material contributes to improve the efficiency of the fusion reactor. This study aimed to fabricate composite materials that have higher thermal conductivity than conventional RAFM steel by adding copper fibers in the steel. To compare the effect of fiber types on the thermal conductivity, copper powder and 3D woven copper mesh were used. The composite materials were fabricated by utilizing spark plasma sintering. To calculate the thermal conductivity of the specimens, their thermal diffusivity and heat capacity were measured by using laser flash apparatus and differential scanning calorimetry. The mechanical properties were also measured by miniature tensile test. 3D copper mesh can effectively improve the thermal conductivity of the composites, but the optimization between their thermal and mechanical properties should be conducted. |
