Abstract: 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 1300 C., a deposit of fine grained beta crystals of silicon carbide are formed. Application of a thin coating of silicon-rich silicon carbide on the surface of the filament both adds strength and provides a surface which is readily bonded to metals, glass and resin matrix materials during the forming of composite structures.
