  • Method for machining holes in composite materials
    Patent number: 4680897
    Abstract: A method for boring well-defined holes in a composite material such as graphite/epoxy. A slurry of silicon carbide powder and water is projected onto a work area of the composite material in which a hole is to be bored with a conventional drill bit. The silicon carbide powder and water slurry allow the drill bit, while experiencing only normal wear, to bore smooth, cylindrical holes in the composite material.
