  • Patent number: 8650820
    Abstract: Method for manufacturing an assembly in a supporting structure, constituted by parts (7,8) made of a fibrous material forming an elongate element that is at least partially hollow (10), with a longitudinal axis of symmetry (9), delimiting an inner area (11) and a outer area (12), characterized in that it consists of achieving the densification on the two end portions (13) of the hollow element, in order to exert, on each of the two end portions of the elongate hollow element, outward tensile forces in opposite directions to each other along its longitudinal axis in order to create an axial prestressing force having a determined value, and to maintain the elongate hollow element in this prestressed condition during the installation of the assembly in the structure. Also described are the assemblies obtained by this method and the structures using such assemblies.
