Abstract
- This paper describes the disruption and sputtering erosions on newly developed SiC doped Carbon fiber reinforced composite (CFC). Disruption experiments were performed under heat fluxes of 1000–2000 MW/m 2 with pulse length of 2–4 ms in the temperature range from RT to 1000°C at the JEBIS facility. Sputtering experiments were performed under the deuterium particle flux of 1–2 × 10 20 m 2 /s with energy of 50–100 eV in the temperature range from 200°C to 600°C at the SLEIS facility. As a result, it is clear that the sputtering yield from 200°C to 450°C is about 0.09 and gradually decreases to 0.067 with increasing sample temperature and that the disruption erosion of SiC doped CFC was about double that of the non-doped CFC and the erosion was mainly caused by the loss of the matrix part.
