Thin wall bushing for robust electrical bonding to fiber-reinforced structures

摘要

A method for directing electrical current to prevent sparking from the interaction between a composite structure and lightning or static electrical charge, the method including the steps of forming a hole in a composite structure; and positioning a bushing into the hole to create an interference fit between the bushing and the composite structure, wherein the bushing is formed of a material that has a coefficient of thermal expansion close to the coefficient of thermal expansion of the composite structure and the bushing provides an electrical path between a fastener disposed in the bushing and the composite structure.
