제목 | SiC coatings for carbon fibers using a thermal-CVD |
초록 | Carbon fibers are considered to be the most potential candidates in various industrial fields because of their high strength, modulus, low density resistance and thermal stability. Unfortunately, carbon fibers exhibit a serious drawback, namely, they are readily oxidized at temperatures as low as 400 ℃. Therefore, various kinds of coating materials are suggested such as tantalum, titanium, silicon, boron carbides. In this study, SiC layers were deposited on preform carbon fibers and carbon composites using a thermal-CVD (chemical vapor deposition) system at 1,000 ℃ and 1,100 ℃ with MTS(methyltrichrolosilane; CH3SiCl4) precursor. Their surfaces were observed using a SEM and their microstructures were investigated using a FE-TEM. |
