Mechanical fixation interfaces are provided in each one of annular longitudinal ends of the section. The fibers are selected from carbon, glass, silicon carbide, aluminum, aramid, vegetal fibers or cellulose. Each interface has a set of inserts inserted in the foam of a sandwich structure of the section.</p> |
