Making a Silicon-Nitride/Silicon-Carbide CompositeHot pressing and nitriding produce strong fiber/matrix material. Fabrication method developed for processing strong and tough silicon-based ceramic composite material, SiC/RBSN, which consists of reaction-bonded Si3N4 (RBSN) reinforced by continuous-length, high-modulus, high strength silicon carbide (SiC) fibers prepared by chemical-vapor deposition method. Increased toughness and ultimate strength of SiC/RBSN composite makes it potential structural material for advanced heat engines.
