Dimensions determination for insulating coatings
First Claim
1. A method for mitigating a propagating brush discharge from an insulating coating covered component, comprising:
- providing a carbon fiber reinforced plastic (CFRP) specimen that represents the component for testing, the CFRP specimen being at least partially covered by a non-conductive insulating coating section of a first surface area and a first thickness;
conducting a test of the CFRP specimen for a propagating brush discharge that results from a capacitance charge in the specimen; and
reducing at least one of the first surface area, the first thickness, a first distance to produce at least one of a second surface area, a second thickness, or a second distance when the CFRP specimen exhibits the propagating brush discharge,wherein the first distance is a maximum distance any portion of the non-conductive insulating coating section is located from an adjacent static dissipative feature.

Abstract
Systems and methods for determining the dimensions of insulating coating sections applied to a conductive component are disclosed. The method includes providing a specimen having an insulating coating section of a first surface area and a first thickness. The method further includes conducting a test of the specimen for propagating brush discharges. If the specimen exhibits propagating brush discharges, the method further includes reducing at least one of the first surface area and the first thickness to produce at least one of a second surface area or a second thickness, or reducing a first maximum distance that any portion of the insulating coating may extend from an adjacent static dissipative feature to produced a second maximum distance. In additional embodiments, insulating coating patterns may be established on the component based on at least one of the dimensions of the second surface area, the second thickness, or the second maximum distance.

18. A method for propagating brush discharge testing, comprising:
-
discharging a carbon fiber reinforced plastic (CFRP) specimen that was charged from a predetermined distance, the CFRP specimen being at least partially covered by a non-conductive insulating coating section of a first surface area and a first thickness; and observing a discharge pattern from the CFRP specimen for at least one of a Lichtenberg pattern or a Lichtenberg discharge leader of a propagating brush discharge; reducing at least one of the first surface area, the first thickness, a first distance to produce at least one of a second surface area, a second thickness, or a second distance when the CFRP specimen exhibits the at least one of the Lichtenberg pattern or the Lichtenberg discharge leader of the propagating discharge; increasing at least one of the first surface area, the first thickness, or the first distance to produce at least one of a third surface area, a third thickness, or a third distance when the CFRP specimen does not exhibit the at least one of the Lichtenberg pattern or the Lichtenberg discharge leader of the propagating brush discharge, wherein the first distance is a maximum distance any portion of the non-conductive insulating coating section is located from an adjacent static dissipative feature.
