  • Patent number: 8408114
    Abstract: A ballistic shield for protection against up to 7.62×63 mm AP rounds (NIJ Level IV). The ballistic shield is multiple layered and includes polymer foam, ceramic tiles, and a support structure fabricated from ballistic resistant fabric. Individual layers are bonded with adhesives and preferably wrapped with fabric. Under the fabric cover of the exterior surface of the shield is a polymer foam layer that exhibits excellent blast impact resistance and blast attenuation properties as well as a hard ceramic or the like layer. The foam layer is preferably made from liquid crystal or semi-crystalline polymer to enhance fire resistance and provide enhanced ductility. According to a preferred embodiment, the man-portable ballistic shield of the present invention also incorporates a compact video system for viewing the front side of the ballistic shield thereby allowing for the elimination of the transparent view port weakness of current state of the art ballistic shields.
