US 8,524,620 B2 · Environmentally stable hybrid fabric system for exterior protection of an aircraft

Abstract

A method of forming an exterior surface protective structure (12) for an aircraft (10) includes uniting a loaded surfacer (52) having a carrier (51) to a hybrid prepreg substrate (32). The prepreg substrate (32) includes a carbon fabric (44) with an integral conductive component (48) having conductivity with in a metal conductivity range and is united to a base substrate (30). The loaded surfacer (52) and the prepreg substrate (32) are cured, which includes interfacially adhering matter between the loaded surfacer (52) and the prepreg substrate (32). A protective fabric system (12) for an exterior (14) of an aircraft (10) includes the base substrate (30). The hybrid prepreg substrate (32) is coupled to the base substrate (30). The loaded surfacer (52) with the carrier (51) is interfacially adhered to the prepreg substrate (32).

Claims13

Dependent claims

A protective fabric system comprising:

a base substrate;
a hybrid prepreg interwoven wire fabric layer disposed over and coupled to the base substrate, the hybrid prepreg interwoven wire fabric comprising carbon fibers in the form of tows woven into a weave pattern, an integral conductive component in the form of metallic wire contained within approximately each of the tows, and a first resin;
and
a loaded surfacer disposed over and interfacially adhered to the hybrid prepreg interwoven wire fabric layer, the loaded surfacer comprising a carrier loaded with at least one inorganic filler and a second resin separate from the first resin, wherein in localized areas the loaded surfacer penetrates through the hybrid prepreg interwoven wire fabric layer to the base substrate.
