Non-metallic composites structures must have some type of
metal incorporated into their design in order to provide
protection from lightning strikes. Flame spraying the composite
structure with pure aluminum is one method of such protection.
Other instances where flame sprayed coatings are used in
non-metallic composites include EMI/RFI shielding, or the
sprayed coating itself can serve as an antenna i.e.-ADF
Antenna Panels.
