“…Recently, a high-crystalline and stoichiometric SiC fiber and an advanced fabrication method have led to great improvement in SiC/SiC composites [6][7][8], based on the same hot-press technique previously reported by the present authors [9][10][11][12]. Consequently, SiC based materials are positioned as an advanced candidate material of fusion reactors.…”

“…However, CVI leaves a typical porosity of 10-15% inside the composite, which leads in particular to a reduction in fatigue and creep-rupture strength. Dense SiC/SiC f composites with a homogeneous microstructure have been recently obtained by applying either a whisker growing process prior to the conventional CVI process [150] or reaction sintering using the sheet stacking hot pressing method [151]. In addition, it was recently demonstrated that the addition of single crystal SiC nano-wires into the SiC matrix is a very efficient reinforcement method for SiC/SiC f composites [152].…”

Current R&D activities on materials for fusion power reactors are mainly focused on plasma facing, structural and tritium breeding materials for plasma facing (first wall, divertor) and breeding blanket components. Most of these activities are being performed in Europe, Japan, the People's Republic of China, Russia and the USA. They relate to the development of new high temperature, radiation resistant materials, the development of coatings that will act as erosion, corrosion, permeation and/or electrical/MHD barriers, characterization of candidate materials in terms of mechanical and physical properties, assessment of irradiation effects, compatibility experiments, development of reliable joints, and development and/or validation of design rules. Priorities defined worldwide in the field of materials for fusion power reactors are summarized, as well as the main achievements obtained during the last few years and the near-term perspectives in the different investigation areas.

“…CVI process has some advantages such as low processing temperature and formation of pure SiC matrix. However, it requires a long manufacturing time, introduces 10%−20% (volume fraction) of voids in the composites and leads to intrinsically porous composites with low thermal diffusivity/conductivity [12].…”

Two-dimensional plain-weave silicon carbide fiber fabric reinforced silicon carbide (2D-SiC/SiC) composites were molded by stacking method and densified through precursor infiltration and pyrolysis (PIP) process. SiC coating was deposited as the fiber/matrix interphase layer by chemical vapor deposition (CVD) technique. Fiber/matrix debonding and relatively long fiber pullouts were observed on the fracture surfaces. Additionally, the flexural strength and elastic modulus of the composites with and without fiber/matrix interphase layer were investigated using three-point bending test and single-edge notched beam test. The results show that the fiber fraction and the porosity of 2D-SiC/SiC composites with and without coating are 27.2% (volume fraction) and 11.1%, and 40.7% (volume fraction) and 7.5%, respectively. And the flexural strength and elastic modulus of 2D-SiC/SiC composites with and without coating are 363.3 MPa and 127.8 GPa, and 180.2 MPa and 97.2 GPa, respectively. With a proper thickness, the coating can effectively adjust the fiber/matrix interface, thus causing a dramatic increase in the mechanical properties of the composites.
