Boeing examines expanded metal foils for lightning protection of composite structures

2014-01-08
A widely used material for lightning strike protection of CFRP structures within the aerospace industry is expanded metal foil (EMF). An issue with EMF is micro cracking of the paint, which can result in corrosion of the metal foil and subsequent loss of conductivity. Boeing researchers examined the issues of stress and displacement in the composite structure layup, which contribute to paint cracking caused by aircraft thermal cycling.
