Abstract

L'invention concerne une fibre d'acier destinée à renforcer des matériaux coulables durcissables, notamment du béton, qui s'étend sensiblement le long d'un axe longitudinal et présente des arêtes longitudinales qui s'écartent de la forme rectiligne. Cette fibre se caractérise en ce qu'elle comprend de fines bandes de tôle d'épaisseur égale (épaisseur de tôle D), dont les arêtes longitudinales, vues en tant qu'arêtes de coupe dans le plan de la tôle, présentent chacune une forme congruente ondulée, sont décalées parallèlement les unes aux autres et sont réunies de manière à former sensiblement une suite de polygones. La largeur du décalage parallèle (b) est tel qu'il subsiste une bande de matériau (largeur d) rectangulaire continue dans le plan de la tôle, entre les arêtes longitudinales ondulées, sur toute la longueur (I) de la fibre. L'invention concerne une outre un procédé permettant de réaliser cette fibre d'acier.
