ABSTRACT:
This invention relates to a process for connecting an element to the end of a tube of composite material, wherein, at least at said end, said tube presents an annular cross-section of which the outer and inner contours are each constituted by a circular line or with interference of shapes, for example polygonal, and said element comprises a recess defined between two spaced apart coaxial prismatic or cylindrical walls, the annular section of said recess corresponding to that of said end so that the latter may be fitted in said element with interposition of an intercalated sleeve made of high-resistance fibers impregnated with resin or polymerizable elastomer. The invention is more particularly applicable to the production of torque tubes or power transmission shafts made of composite material.
