Abstract

Un produit intermédiaire composite à base de segments de fibres noyées dans une matrice de résine, caractérisé en ce qu'il se présente sous la forme d'un tapis (20) comportant un empilement de couches (10) de segments (11) plats multifibres. Les segments sont disposés en juxtaposition, les segments (11) d'une même couche (10) étant orientés selon une direction unique, et lesdits segments (11) sont liés, pour certains d'entre eux au moins, par adhésion au droit de leurs zones de croisement-superposition avec les segments de couches (10) de segments (11) adjacents. De cette manière, l'empilement de couches (10) forme un tapis (20) de masse et d'épaisseur constante, de faible cohésion propre présentant une souplesse relative.
