In this structural element, the end fittings 1 are mechanically connected to a thermoplastic core 3, having mechanical properties suitable for the application, around which core is wound the reinforcing filament winding 2. This core is solid, or tubular and, in this case, is filled with a synthetic material which is expanded or kept as it is. It can be internally reinforced by means of a reinforcing ply. Such an element can be used for manufacturing shafts, cranks, tension rods, torsion bars, structural elements for an antenna, a pylon, a hanger, for removable roofing, structural elements for buildings and roof frames, and all elements for industry. <IMAGE>
