Abstract

L'invention porte sur un panneau de blindage ayant une face d'impact. Le panneau de blindage comprend au moins une couche absorbante rigide et une couche de confinement à résistance à la traction élevée entourant la ou les couches absorbantes rigides. La ou les couches absorbantes rigides peuvent avoir une pluralité d'éléments de protection en forme de bande, qui adhèrent les uns aux autres le long d'un plan sensiblement orthogonal à la face d'impact. La ou les couches absorbantes rigides peuvent être constituées en un matériau vitrocéramique ayant un coefficient de dilatation thermique sensiblement égal à zéro, et qui, lors de l'impact par un projectile, le convertit en une énergie de dilatation au moins dans une zone d'impact.
