A configuration and manufacturing method for a trailing edge of an aircraft airfoil, such as a control surface or a lifting surface is described. The trailing edge is formed and configured by upper and lower composite covers, which are stitched to each other with a metallic wire, such as the metallic wire is electrically in contact with upper and lower metallic meshes to provide electrical continuity between meshes. According to a method, upper and lower covers configuring the trailing edge, are stitched with the metallic wire before curing the covers, so that the metallic wire gets embedded within the composite material. A trailing edge for an aircraft airfoil, which is easy to manufacture and that at the same time fulfills aerodynamic, mechanical and electrical conductivity requirements is described.

The tapes of fibrous material(s) include continuous fibers impregnated with at least one thermoplastic polymer, and optionally a chain extender. The web has a surface, in cross-section perpendicular to the axis of the fibers, S, that is substantially equal to the sum of the surface, in cross-section perpendicular to the axis of the fibers, of each initial individual tape, denoted S.sub.th, S.sub.th being equal to NIEp, wherein l represents the average width of a tape and Ep represents the average thickness of a tape, N being between 2 and 2000, and the average thickness of each individual tape being less than or equal to 150 m.

Methods and apparatus to form venting channels on a panel for a decorative layer are disclosed. An example method includes contacting an outer surface of a tool to an outer resin layer of a panel. The outer surface of the tool has protrusions. The example method includes moving the outer surface of the tool on the outer resin layer of the panel in a first direction to cause the protrusions of the tool to form first venting channels on the outer resin layer of the panel and coupling a decorative layer to the outer resin layer of the panel via an adhesive layer. The first venting channels are to vent at least one of gas or vapor away from the decorative layer to deter separation of a portion of the decorative layer from the outer resin layer.
