ABSTRACT:
In a laminated structure, such as a structural component of an aerospace vehicle or the like, which is fabricated of layers of filament composite material, means is provided for protection against lightning strike damage and electromagnetic interference. In particular, the outer surface layer of the filament composite material is fabricated of conductive metallic-coated filaments to provide a conductive barrier to disperse the current from lightning or other electromagnetic sources. The filaments may be fabricated of a composite material such as glass which has an aluminum coating. The structure may be woven or filament wound with intermixed resin, and the metallic-coated filaments are cured simultaneously with the entire laminated structure of filament composite material.
