“…Carbon fiber has some advantages, such as high strength and high modulus at high temperature. Carbon fiber-reinforced SiC material has many excellent properties, such as low density, low linear expansion coefficient, oxidation resistance, creep resistance, chemical resistance, high resistance to thermal shock, salt fog, and electromagnetic wave absorption characteristics, in addition to the intrinsic properties of SiC [32][33][34][35][36][37]. Furthermore, carbon fiber-reinforced SiC composites do not perform brittleness in the fracture process, carbon fiber-reinforced SiC has a high thermal conductivity property, and it will be improved with the development of science and technology [38,39].…”

Silicon carbide (SiC) is considered as an important material for nuclear engineering due to its excellent properties. Changing the carbon content in SiC can regulate and control its elastic and thermodynamic properties, but a simulation study of the effect of carbon content on the sputtering (caused by the helium ions) of SiC is still lacking. In this work, we used the Monte-Carlo and molecular dynamics simulation methods to study the effects of carbon concentration, incidence energy, incident angle, and target temperature on the sputtering yield of SiC. The results show that the incident ions' energy and angle have a significant effect on sputtering yield of SiC when the carbon concentration in SiC is around 62 at %, while the target temperature has a little effect on the sputtering yield of SiC. Our work might provide theoretical support for the experimental research and engineering application of carbon fiber-reinforced SiC that be used as the plasma-facing material in tokamak fusion reactors.
