Abstract

L'invention concerne un stratifié à l'épreuve des coups de couteau (1) qui comprend des super-fibres, le stratifié à l'épreuve des coups de couteau comprenant : des tissus renforcés par une résine (3a-3e) obtenus par incorporation de résine dans un tissu dans lequel des super-fibres sont utilisées pour la chaîne et la trame ; et des tissus non tissés (2a-2d) constitués principalement des super-fibres. Les tissus non tissés (2a-2d) sont structurés de façon à être pris en sandwich par les tissus renforcés par une résine (3a-3e) depuis les deux surfaces. Lorsqu'un impact par un objet tranchant se produit, le mouvement des fibres constitutives du tissu non tissé (2a-2d) pris en sandwich par les tissus renforcés par une résine (3a-3e) depuis les deux surfaces est rendu impossible, ce qui amène les fibres constitutives des tissus non tissés (2a-2d) à être tirées dans le sens de la longueur, absorbant ainsi l'énergie d'impact. L'instrument à l'épreuve des coups de couteau selon la présente invention est configuré pour recevoir les tissus non tissés dans un état pris en sandwich par les tissus renforcés de résine depuis les deux surfaces, ou dans un état dans lequel les tissus non tissés et les tissus renforcés de résine sont empilés en alternance. Ladite configuration empêche des fibres à haute résistance et à module élevé de se déplacer lors d'un impact par un objet tranchant, et amène une contrainte dans la direction d'engagement à agir sur la fibre, et permet ainsi une absorption efficace de l'énergie d'impact.
