Abstract
Abstract A graphite-fibre reinforced structure (1) capable of withstanding lighting strikes (10) comprises at least one ply (2) of bonded graphite fibres (8) with metal wire or metal coated filament (7) woven therein in both the warp and fill directions to increase the capability of the laminate to withstanding lightning strike currents without significant damage.
