Abstract
An aircraft component includes a composite structure and a metallic circuit on a film. The film is co-cured with the composite structure. The metallic circuit is patterned to dissipate energy generated by lightning strikes on the composite structure. The metal circuit is also patterned to provide connectivity for multi-function apparatus.
Claims11
An aircraft component comprising:
- a composite structure;
- and
- a metalized surface on a film, the film co-cured with the composite structure, the metalized surface patterned to dissipate energy generated by lightning strikes on the composite structure, the metalized surface also patterned to provide a plurality of conductive traces to provide connectivity for multi-function apparatus;
- and electronic devices electrically connected to the traces.
