A braided member (33) has a longitudinal axis (37) and a plurality of braided strands of structural fiber (39). At least one elongate member (35) having a rigidity greater than that of the strands of structural fiber is intertwined into the braided member. According to the preferred embodiment of the present invention, the structural fibers (39) are selected from the group consisting of aramid, glass, and carbon fibers and the braided member is a triaxially braided tube. According to the preferred embodiment of the present invention, the elongate member (35) is a pultruded rod having compressive strength approaching its tensile strength.
Un élément tressé (33) comporte un axe longitudinal (37) et plusieurs torons tressés d'une fibre d'armature (39). L'un, au moins, des éléments de forme allongée (35), d'une rigidité supérieure à celle des torons d'une fibre d'armature, s'entrelace dans l'élément tressé. Comme en témoigne la réalisation préférée de cette invention, on choisit les fibres d'armature (39) dans le groupe constitué de fibres anamides, de fibres de verre et de carbone tandis que l'élément tressé est un tube tressé triaxial. Egalement au titre de la réalisation préférée, l'élément de forme allongée (35) est une tige pultrudée dont la résistance à la compresion se rapproche de sa résistance à la traction.
