Patent ID: 8248748

Claim:
Ducting for a fuel pipeline of an aircraft or spacecraft, the ducting comprising at least one multilayer pipe having two respectively inner and outer layers, each 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 from each other by an intermediate layer capable of stiffening the pipe when flexed and/or to insulate it electrically, characterized in that each of the inner and outer layers has at least one winding with contiguous turns around the axis of symmetry (X) of the pipe, of a continuous element made of a composite thermoplastic material with a thermoplastic matrix incorporating these reinforcing means, so that this pipe enables electrostatic charges to be eliminated through its inner layer and electric charges due to lightning to be deflected through its outer layer while having a high modulus of inertia and reduced mass.
