Abstract
A process for the manufacture of an elongate composite element comprising a bundle () of multifilament fibers embedded in a composition based on a polymerizable substance comprising the following comprises: arranging multifilament fibers in the form of several individual strands, so that a first strand () is located at the center of the bundle and that the other strands are positioned around the first strand; and carrying along the arrangement of multifilament fibers in order to subject it, in the direction of forward progression, to degassing of said arrangement of fibres by the action of vacuum, impregnation of the arrangement of fibres with the composition, passage of the first impregnated strand through a first die () which carries out its partial polymerization, passage of all the strands through a last die () which brings them together in a single strand (), and exposure of the single strand () to a source of radiation in order to carry out an additional polymerization to obtain the elongate composite element.
