Abstract:
1. A seal for attenuating energy from an electrical discharge across an interface, the seal comprising: a cover defining an inner volume shaped to enclose said interface; and a filled sealant including a semi-rigid sealant mixed with a filler having a multiplicity of discrete particles of different composition than said semi-rigid sealant, said particles having a selected one or both of a crush strength and a burst strength less than a corresponding crush strength and burst strength of said semi-rigid sealant, said filled sealant being contained within said inner volume such that said filled sealant is adjacent said interface when said cover is placed over said interface; whereby said particles absorb energy in the form of expanding gases resulting from a lightning strike or other high voltage discharge and are crushed.
