Abstract
The invention relates to a ducting for a fuel pipeline of an aircraft or spacecraft designed to be mounted in each of the wings of an aircraft, an aircraft wing incorporating this ducting and a method for producing same. This ducting comprises at least one multilayer pipe having two respectively inner and outer layers made of a composite plastic material that is leakproof and chemically resistant to the fuel and that is reinforced by electrically conductive reinforcing means, these layers being separated by an intermediate layer, notably capable of stiffening the pipe when flexed and/or to insulate it electrically. Each of the inner and outer layers has at least one winding with contiguous turns of a continuous element made of a composite thermoplastic incorporating these reinforcing means.
