Abstract

SiC long-fiber-reinforced SiC composites was made by using carbon-coated SiC fiber (Tyranno SA). The carbon coating was formed by a heat-treatment at 1700°C-1800°C under vacuum for 0.5h-2h. SiC/SiC composites were fabricated by hot-pressing at 1700°C under a pressure of 40MPa using Al2O3-Y2O3-CaO system as sintering additives. Effects of fiber coating on mechanical properties of obtained composites were evaluated.
