TL;DR: SiC fiber-reinforced SiC matrix composites (SiC/SiC) are being considered as a candidate structural material for fusion reactors because of their low induced radioactivity by 14 MeV neutron irradiation and high-temperature strength.

TL;DR: In this article, the authors present an overview of some of the recent issues regarding the use of low activation material including the radiation performance of present day materials and the direction towards the development of radiation hardened SiC composites.

TL;DR: In this article, the current status of SiC/SiC R&D is reported and it is demonstrated that future activities require a strong collaboration with the industry as well as common efforts involving the different laboratories.

TL;DR: In this article, SiC fibers and fiber/matrix interfaces made with porous SiC and multi-layer SiC/C/SiC are developed to minimize the presence of C in the interface for improved radiation and chemical stability of the composite materials.

TL;DR: An overview of the current status of the European R&D activities on SiCf/SiC composites focussing on reactor design studies, composites manufacturing, material characterisation in particular after irradiation, chemical compatibility with different blanket environments and development of joining techniques is presented in this paper.
