A ducting and associated method is provide in which the ducting includes a pipe with a thermoplastic or thermoplastic elastomeric layer and a reinforcing layer. The pipe has a curved or bent geometry and the reinforcing layer is made of a composite material based on reinforcement in intimate and direct contact with the subjacent layer. The geometry is obtained by hot forming the inner layer to give the geometry, and the reinforcement is either impregnated with a thermosetting matrix to form a thermosetting composite, or reinforcing fibers are intermixed with thermoplastic fibers or powders, or impregnated with a plastic polymeric coating that is curable chemically. Alternatively, the inner layer is first covered with the reinforcing layer in which the reinforcement includes reinforcing fibers intermixed with a thermoplastic material in the form of fibers, film or powder is blow-molded to give the pipe its final geometry.

Ducting for a fluid transfer pipeline for an aircraft or spacecraft, method for producing same and aeronautical structure incorporating same

The present invention relates to a ducting for a fluid transfer pipeline for an aircraft or spacecraft, an aeronautical structure incorporating it and a method for producing this ducting. The ducting () comprises a pipe () with a thermoplastic or thermoplastic elastomeric layer () and a reinforcing layer () surmounting it. The pipe has a curved and/or bent geometry and the reinforcing layer is made of a composite material based on reinforcing means () that are in intimate and direct contact with the subjacent layer, such as the inner layer, said geometry being obtained by one or other of the following two methods (a) and (b):

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.
