Lightning protection utilizing lightweight electrically conductive coatings
with a conductance of approximately 220 to 350 mhos per square co-cured or
secondarily bonded to the outer surface of thin skin composite structure.
Selection of either 2 to 3 ounces per square yard or aluminum mesh of 1 to
1.5 ounces per square yard, depending on corrosion compatibility, satisfy
the conductance requirement and has shown superior lightning protection
over heavier weight conductive coatings.
