A method of strengthening a bolt hole in a fibrous composite laminate when a hole is drilled in a laminate sheet. The method allows for increased thickness strength, bearing strength and the use of low cost high strength fasteners which may or may not be galvanically compatible through the use of plating the edges of the holes with a metal spray.
