METHODS OF FASTENING COMPOSITE AIRCRAFT SKINS

摘要

An anti-lightning fastener for joining an aircraft skin panel 5 made of composite material to a substructural member 6, comprising a bevel headed countersunk bolt 1 and captive nut 4, wherein the bolt 1 has a head surface region 8 of an electrically conductive material 10 for contact with the outer plies 11 of the skin panel 5, and a shank surface region coated with a layer 12 of electrically insulating material for contact with the inner plies of the skin panel and substructural member, whereby lightning is conducted and dissipated controllably and without arcing into the aircraft structure.
