(X-Post) Hiring process assignment : Lighting Strike Protection (LSP) for composite aircraft knowledge needed

So far what I’ve learned from the article and how I would structure my report

Point 1 Sum up LSP goals :

LSP strategies have three goals: provide adequate conductive paths so that lightning current remains on the structure's exterior; eliminate gaps in this conductive path to prevent arcing at attachment points and ignition of fuel vapors; and protect wiring, cables and sensitive equipment from damaging surges or transients through careful grounding, EMF shielding and application of surge suppression devices where necessary

Then I would review LSP technology categorized as :

The standard: Metal mesh Metal mesh and expanded foil (copper and aluminum)

Integrated LSP materials Many aerospace suppliers offer expanded metal mesh precombined with adhesive films, surfacing films or prepregs.

Metallized fibers, fabrics & veils a highly conductive nonwoven veil made with randomly oriented nickel or copper-coated-carbon fibers.

Conductive surface treatments as last category and as a would-be future trend ?

Extensive testing has compared UltraConductive to expanded metal and other technologies. Results indicate that the Lord spray and film products exhibit 78 percent lower resistance than a conventional conductive epoxy yet perform like an equivalent test panel protected by expanded copper foil in terms of sustained damage, at half the weight. “Our tests have shown that a carbon composite coated with UltraConductive achieved 121 dB of EMI shielding,” he reports, “equivalent to that of a solid 1-mm [0.04-inch] thick aluminum skin. Thus, Ultraconductive enabled the carbon composite to shield just as well as solid aluminum.” The sprayable and film products are undergoing qualification testing with several aircraft OEMs. “These products give designers multiple options for LSP and EMI shielding, and they can work with other materials across the entire aircraft.”
