Abstract

The bond between a tile made of carbon fibre composite (CFC) and a metallic heat sink is similar to a ceramic/metal bond. It is difficult to perform due to the mismatch between the material expansions, which create high internal stresses. However in the Tore Supra controlled fusion machine (CEA Cadarache, 13108 St Paul Lez Durance, France), this kind of bond, in development since many years, has allowed a 7.6 m2 toroidal limiter to be achieved, which led to perform CFC/metal bonds for more than 12 000 tiles. The used process consists of a geometrical structuring of the CFC surface to be joined, using a laser treatment, which allows a good mechanical coupling of the tile to the brazing material or cast metal.
