ABSTRACT:
A lighting strike coating composition for composites. The composite is multilayered and comprises (i) a prepreg containing layer, (ii) a lightweight, highly conductive metallic wire screen or foil layer, and (iii) a sheet of lightweight carrier fabric containing (a) on one side a coating of a highly filled, thermoset resin in which the filler comprises a multimodal combination of filler particles, and (b) optionally, on the other side an adhesive joining it to layer (ii); wherein the layers are bonded to each other. Also, a process for making the multilayered composite by bonding prepreg assemblies, optionally with a honeycomb structure, to at least one layer of conductive metal screen or foil, bonding the metal screen or foil to one surface of a carrier fabric sheet that is normally not conductive, the other side of the carrier sheet is bonded to the surface coating of a highly filled, thermosettable resin in which the filler comprises a multimodal combination of filler particles, whereby to form a composite assembly, subjecting the composite assembly to sufficient heat to cure the prepregs, honeycomb structures and the surface coating to form a cured composite structure.
