Abstract
A composite reinforcement element comprising three superimposed and crossed even layers of threads and a continuous thread extending perpendicularly through the three superimposed even layers. The layers are impregnated with a binder and the binder is polymerized after impregnation. The superimposed and crossed even layers are initially maintained assembled, before the impregnation and the polymerization of the binder, by a conjugate action of gripping and friction of the three superposed and crossed even layers of threads on the continuous thread which extends therethrough. The continuous thread forms an internal surface of the composite reinforcement element which protrudes from the superimposed and crossed even layers of threads in the form of open loops which are interconnected on an external surface of the element.
