    摘要: Silicon carbide filament is produced by overcoating a carbon monofilament core using continuous process vapor deposition. The deposition takes place by passing the carbon monofilament through a reactor into which gaseous sources of silicon and carbon are injected. At a deposition temperature of about 2370.degree. F., a deposit of fine grained beta crystals of silicon carbide are formed. Application of a thin protective coating of boron-based refractory material on the surface of the silicon carbide filament both adds strength and provides a surface which is readily bonded to both metals and epoxy matrix materials during the casting of composite structures.
