PROGRESS OF SILICON CARBIDE FIBERS AND THEIR APPLICATION TO CERAMIC MATRIX COMPOSITES

摘要

Silicon carbide fibers have high strength and high modulus and they are provided with flexible, multi-filament yarn. Durability test was demonstrated to provide superior property among kinds of ceramic fibers under heat and stress in oxidative environment (Figure 1). It was in 1975 that SiC fiber was invented by converting organosilicon polymer into ceramics by pyrolysis. Thereafter Nippon Carbon industrialized SiC fiber, Nicalon™, in 1983.
