The invention provides a composite armor plate for absorbing and dissipating kinetic energy from high-velocity projectiles, the plate comprising a single internal layer of pellets which are bound and retained in plate form by an elastic material, substantially internally within the elastic material, such that the pellets are bound in a plurality of spaced-apart rows and columns, the pellets being made of ceramic material, and the pellets being substantially fully embedded in the elastic material so that the pellets form an internal layer, wherein the solidified material and the plate are elastic, and wherein a majority of each of the pellets is in direct contact with six adjacent pellets in the same layer to provide mutual lateral confinement therebetween, each of the pellets being characterized by a body having a substantially regular geometric cross-sectional area and first and second end faces, each of the end faces projecting from the body and having an outwardly decreasing cross-sectional area wherein the height of the end face disposed substantially opposite to an outer impact receiving major surface of the plate is less than 15% of the length of the diameter of the pellet body from which it projects.
L'invention se rapporte à un blindage en composite conçu pour absorber et dissiper l'énergie cinétique de projectiles animés d'une grande vitesse. Celui-ci comprend une couche interne unique de granules en céramique liés et maintenus en forme de plaque par un matériau élastique dans lequel ils sont substantiellement noyés de façon à être disposés en rangées et en colonnes espacées formant une couche interne dans laquelle le matériau renforcé et le blindage sont élastiques, et où une majorité des granules sont en contact direct avec six granules adjacents de la même couche de façon à empêcher efficacement le passage de projectiles dans les interstices. Lesdits granules se caractérisent par la présence de formes géométriques substantiellement régulières et d'un diamètre décroissant sur deux faces protubérantes principales opposées au corps conçues pour absorber l'impact. Le blindage représentent moins de 15 % de la longueur du substrat.
