Abstract

La présente invention concerne un tissu textile de renforcement stabilisé et son procédé de fabrication, la résine thermoplastique apte à la fusion étant utilisée comme résine stabilisatrice, ce qui permet à la résine d'être utilisée dans l'application de stabilisation de tissus non crêpés obtenus à partir de fils comportant les fibres de renforcement afin d'imprégner davantage la structure en vue de mieux stabiliser les fils de renforcement. La stabilisation permet de rendre plus stable et plus contrôlable l'espace situé entre les fils comportant le fil de renforcement de la structure. Un autre but de la présente invention consiste à permettre à la structure de renforcement d'offrir une facilité d'utilisation pendant la fabrication du composite et à permettre au matériau composite d'avoir des valeurs de résistance plus homogènes. Le tissu sec obtenu par ce procédé de fabrication permet la fabrication aisée d'éléments composites complexes.
