Lord Corp. (Cary, N.C.) introduced at SAMPE 2012 UltraConductive Film and Coatings for lightning-strike protection. The product, an epoxy resin with a proprietary conductive filler, can be cocured with composite aircraft structure as an in-mold surfacing film or as a spray coating, replacing traditional expanded metal meshes and foils. Reportedly offering a 55 percent direct weight savings as compared to copper, the new product also reduces the amount of primer and paint needed to achieve a smooth part surface. Lord reports that UltraConductive can be readily repaired, is not affected by salt corrosion or sun exposure, and does not negatively impact part mechanical properties.
