Joining of CFC composites for thermonuclear fusion reactorsFunded under: JRC-FUSAFE 5C
High thermal conductivity carbon fibre reinforced carbon (CFC) composite is a very promising material for the structures directly facing the plasma in future fusion reactors. Its low atomic number limits radiation losses in the plasma; it can operate at a much higher temperature than other candidate materials such as beryllium and it has an excellent thermal shock resistance and a very low induced-activation. Unfortunately its use as a structural material is problematic since it cannot be welded and only limited machining of the composite is possible. The development of appropriate joining techniques is therefore essential. Suitable joining materials were selected compatible with the low activation material (LAM) and joining criteria. These materials were either metallic (e.g Si, Ti) or glass-ceramic (e.g borosilicates, lead borates). The joints were then characterised by thermal analysis and morphological examination of the interface.
