A structural part for lightning strike protection, preferably of an aircraft includes a first structure element, wherein the first structure element includes a conducting material and is adapted to conduct electric currents into a grounded conducting airframe structure, and a second structure element, wherein the second structure element includes an outer layer with a first surface, wherein the outer layer includes a composite, preferably carbon-fibre reinforced plastic, CFRP or glass-fibre reinforced plastic GFRP. The structural part further includes a first elongated, preferably wedge-shaped, electrical conductor, with a first end and a second end, wherein the first end of the first elongated electrical conductor is connected to the first structure element and extends through the second structure element to the first surface, so that the second end of the first elongated electrical conductor serves as a lightning receptor without impairing the radar cross section of the aircraft.

A method of making an electrically-conductive film is provided. The method includes providing a release layer, optionally having a topologically structured surface, and depositing at least one electrically-conductive layer on the release layer whereby the at least one electrically-conductive layer has an outer surface that substantially replicates the topologically structured surface. The electrically-conductive layer can be peeled away from the release layer to obtain the electrically-conductive film. Such electrically-conductive films can be useful in lightning strike applications.

A sealed component assembly within an aircraft, comprising first 10 and second 12 components each facing surfaces, and a sealing member 20 extending between the facing surfaces. The sealing member includes a conductive portion 22 sandwiched between first 24 and second 26 sealing portions. The sealing portions extend between and in contact with the facing surfaces, and are made of a sealing material. The conductive portion is in contact with conductive regions of the facing surfaces and defines an electrical connection therebetween. The conductive portion is more conductive than the sealing portions. In a particular embodiment, the components are a floor panel and a floor beam. A sealing member 20 for a connection between two aircraft components is also discussed.
