SiC/SiC composites

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

SiC is an exceptional ceramic compound that offers high temperature capability, neutronic transparency, low activation/low decay heat, and exceptional radiation tolerance. SiC/SiC is a class of ceramic matrix composites (CMCs) that combines these intrinsic properties of SiC with engineered advantages of the continuous fiber-reinforced composites to make a structural material. The applications of SiC/SiC composites to fusion power plant concepts have been studied for decades. The proposed applications include the blanket/first wall structures, the flow channel insert for liquid metal blankets, and the divertor components. In this section, typical requirements to the SiC/SiC composites in these applications are introduced, followed by a brief overview of status of the material development. Finally, the remaining key technical challenges and the resulting research and development priorities are discussed.
