ABSTRACT:
A method of joining a tube of composite material and a tubular metal fitting includes, winding filaments of pre-impregnated fibers to produce a tube with a longitudinal axis. The fibers that provide tensile strength for the tube are at a tensile fiber angle relative to the longitudinal axis. A tubular metal fitting is introduced at least partially into an end of a tube section, with inner and outer parts of the fitting being located inside and outside of the tube section. The inner and outer parts are secured by inserting penetrating elements extending radially through the tube section and the parts of the fitting. The penetrating elements are arranged in uniform circumferential alignments which are equally spaced from each other along the longitudinal axis. Each circumferential alignment defines an alignment plane perpendicular to the longitudinal axis and spaced by a distance which is a function of an integer, the number of circumferential alignments, the interval between two consecutive penetrating elements in the same circumferential alignment and the tensile fiber angle.
