Abstract : A first wall of a controlled thermonuclear reactor made of a graded silicon carbide/aluminum composite material that may be fabricated by the plasma spraying of a composite of aluminum matrix containing SiC fibers or a graphite/aluminum composite material. In an alternative method of manufacture, dry Al powder is mixed with silicon carbide or graphite fiber, cold pressing, heating, hot pressing in molten or semi-molten state by extrusion of the Al-SiC composite, having an aluminum matrix containing SiC or graphite in a graded stratum, with one face of the wall consisting of essentially pure Al and SiC gradually increasing in contact to the other face of the wall has maximum of 30-40% SiC or graphite fibers and 70-60% Al that exhibits superior properties in containing the nuclear reaction.
