Shield interlayer for spall suppression
Abstract
Abstract A DUAL LAYER COMPOSITE LAMINATE CONSISTING OF BALLISTIC NYLON FELT WITH A PERIPHERAL SEAL COAT AND A URETHANE ELASTOMER, BONDED TO THE INTERNAL SURFACE OF A WALL, FLOOR, OR OTHER PART OF VEHICLE STRUCTURE. THE FELT SIDE IS PLACED AGAINST THE STRUCTURE, TO BE PROTECTED, AND THE URETHANE SIDE IS EXPOSED. THE NYLON FELT IS AN EFFICIENT FRAGMENT CATCHER, AND ALSO PROVIDES STAND-OFF WHICH ALLOWS THE CONE OF SPALL TO EXPAND AND BE SUPPRESSED INSTEAD OF FOLLOWING THE PROJECTILE DIRECTLY THROUGH THE WOUND. THE URETHANE ELASTOMER SURFACE IS HIGHLY RESTRICTIVE AND TEAR RESISTANT. IT CONSTRICTS THE SPALL PATTERN AND KEEPS THE FELT FROM SPREADING EXCESSIVELY AS A PROJECTILE PASSES THROUGH.
