Silicon carbide (SiC) is a promising candidate for such a material due to its excellent oxidation, corrosion and creep resistance (). On the basis of such a background, the present work describes the enhancement of oxidation resistance, due to the surface coating of VGCF with SiC via the carbothermal reduction of a silica precursor/silica layer formed from tetraethyl orthosilie (TEOS) using

1/2/1994· Therefore, the silicon carbide fiber is a high-strength silicon carbide fiber having a very excellent heat resistance. Action The irradiation of a precursor fiber prepared through the spinning of a polycarbosilane with a radiation in an oxygen-free atmosphere or in vacuo causes a crosslinking reaction in which oxygen does not participate to occur, so that the precursor fiber becomes infusible.
