1. A method to mitigate electrical surface discharges from insulating coatings applied to a substrate, comprising:
- applying a first insulating primer layer to a metallic component; and
applying a second insulating primer layer discontinuously to a surface of a carbon fiber reinforced plastic (CFRP) component which is to be secured adjacent the metallic component at a position designated an attachment footprint to form a plurality of primed surface portions and at least one unprimed surface portion positioned between the plurality of primed surface portions, wherein the plurality of unprimed surface portions are positioned at least 1.75 inches from the metallic component, andwherein the at least one unprimed surface portion enables electrostatic dissipation from the surface of the second insulating primer layer into the CFRP component.

Abstract
Systems and methods for discontinuously applying an insulating primer to a carbon fiber reinforced plastic (CFRP) component are disclosed. In one embodiment, a method for mitigating electrical surface discharges from a CFRP component includes first applying an insulating primer to a metallic component. Next, an insulating primer is applied discontinuously to the CFRP component adjacent the metallic component. The discontinuous application of the insulating primer forms a primed portions and unprimed portions. The unprimed portions are configured to enable electrostatic dissipation.
