Excerpt
Excerpt: (U) An SBIR Program is developing and demonstrating the technology necessary to design and fabricate an elastomer encapsulated ceramic tile array using low-cost and high-volume production methods. The armor system utilizes a continuous elastomer encapsulation surrounding ceramic tiles in the array. The elastomer prevents or greatly reduces the damage done to tiles adjacent to impacted tiles by attenuating the lateral stress waves produced. The elastomer also decouples the ceramic tiles from the general, late time response of the target backing. This encapsulated array technology may be employed as the hardface component of structural armor, for parasitic applique armor systems, and as armor upgrade to existing vehicles which contain metallic or composite hull/turret structures. Ballistic testing of small tile arrays has enabled the construction of a Second Hit Ballistic Performance Map for an armor system composed of encapsulated ceramic tile array and an aluminum backing plate. This system has been designed to protect against multiple hits of the threat spaced three inches from previous hits. The Map enables optimization of the armor system for a particular application. The permanent deformation of the backing plate after each hit was characterized because control of backing deformation is an important factor in achieving protection against proximate multiple hits. Targets, designed to represent a portion of a full-scale armor, were fabricated as 4 X 4 tile arrays using mass production methods. Ballistic testing of these targets demonstrated their ability to defeat six impacts of the AP projectile at muzzle velocity.
