Composite materials for tokamak wall armor, limiters, and beam dump applications

Abstract A new generation of composite materials, graphite fiber reinforced metal carbides and borides, is being develop, ed. These materials have high strengths and excellent chemical and mechanical stability. Their properties can be tailored over wide ranges to meet service requirements. By using components such as boron, silicon or titanium, these composites offer promise as low Z number materials for limiters, wall armor, beam stops, etc., in Tokamaks.
