【Abstract】 In this study polytitanocarbosilane (PTC)was used as the polymer precursor to form a layer of SiC coat containing Ti on the surface of carbon fiber after high-temperature sintering. This layer of coating consisted of TiC and SiC mixed crystals. It had a series of excellent properties such as good stability, low density and close-packed structure. The properties of antioxidation and surface moistening were greatly improved by this method.更多还原
