  • Publication number: 20110107904
    Abstract: The armor system according to the present invention also exploits synergistic multi-layering to provide different properties as a function of depth within a sandwich panel. Various embodiments of the invention include a combination of composite sandwich topology concepts with hard, strong materials to provide structures that (i) efficiently support static and fatigue loads, (ii) mitigate the blast pressure transmitted to a system that they protect, (iii) provides very effective resistance to projectile penetration, and (iv) minimizes shock (stress wave) propagation within the multi-layered armor sandwich structure. By using small pieces of highly constrained ceramic, the concept has significant multi-hit potential.

  • Publication number: 20110088541
    Abstract: This disclosure teaches the use of low density, “open”-structure glasses as backing glasses, behind glass-ceramic strike-faces, in transparent armor composite windows. These low density “open-structure’ glasses are sometimes referred to as “anomalous” glasses. For transparent armor applications both silica, including fused silica, and borosilicate glasses can be used as backing glass. These backing glasses provide improved ballistics performance over that of standard commercial soda lime backing glass. These glasses should be used either in their as-formed state (e.g. float surfaces) or should be finished using a process designed for minimizing sub-surface damage.

  • Publication number: 20110023697
    Abstract: A flexible armor system adaptable to a garment suitable for extremity protection uses a planar array of polygon-shaped solid elements which detach upon projectile impact and combine their mass with the projectile for reduced velocity and increased impact area. The solid elements are bonded between an elastic strike-side spall cover and a high tensile strength flexible backer layer, and are further supported by a substantial fiber pack. In embodiments, the solid elements are ceramic, and are commutated but remain essentially intact after the projectile impact. Edge bars can cover junctures between solid elements, and center buttons can cover intersections between the junctures. Edge bars and center buttons can also be ceramic. The ceramic parts can include titanium backing layers. After formation, ceramic cores can be compressed upon cooling by an outer ceramic layer having a higher coefficient of thermal expansion, the outer layer being formed by glazing or doping.
