International Classification:

H02H 1/00

US Classification:

361218, 361117

Abstract:

A lightning-protected conductive composite fuel tank includes a conductive material arrayed on an outer surface to at least partially cover a fastener centerline. Through holes extend along the fastener centerline through the conductive material and the underlying fuel tank shell. These through holes are countersunk into the fuel tank shell to a depth such that a fastener in a through hole will avoid electrical continuity or communication with the conductive material on the fuel tank outer surface. The gap in the countersunk through holes, between the fastener heads and the coextensive outer surface of the fuel tank, is filled with a dielectric or nonconductive material.

Abstract:

The different illustrative embodiments provide a method and apparatus for installing an edge seal. In one illustrative example, a pre-cured edge seal is placed on an edge of a composite structure with a sealant to form a placed pre-cured edge seal. The placed pre-cured edge seal is then cured on the composite structure.In another illustrative embodiment, an edge of a structure is prepared with solvent, and a brush coat of sealant is applied to the top and the edge of the structure. A fillet is applied to the base of the edge of the structure. A pre-cured edge seal is applied to the edge of the structure, and the edge is cured.
