Abstract : A light weight armor for combat vehicles, having at least three laminations; an outer layer of quenched and tempered high-hardness alloy steel to induce projectile shatter, and being the layer which is directly exposed to ballistic attack; a unique second lamination or core of a low-density, high-strength material; and an inner (the third) lamination of high-toughness, quenched and tempered alloy steel of medium hardness for spall resistance; the 'sandwich' is sealed with a closure of edge pieces of low-carbon, low-alloy steel for easy fabrication of the assembly which may be three layers of similar or dissimilar materials. The critical element for optimum performance of the composite armor arrangement is the second lamination or core. (Author)
