As the aerospace industry continues on its quest for ever-increased efficiency, so goes the quest for ever-more composite content on aircraft. And with it, more opportunities to repair it. Typical composite panel fiber reinforcements are carbon, aramid, and fiberglass. The machining techniques for these typical composite materials are similar, but minor differences exist, such as the style of cutting tool or drill bit. Automated drilling methods that may be used during original manufacture are rarely used in typical composite repair situations.
