An armor assembly configured to be mounted to a vehicle to protect it from an expected explosion. The armor assembly comprises at least two layers, each contacting an adjacent one of said layers. One of said layers is a perforated layer and another one is a covering layer. The perforated layer is made of a material of a first density, and having a first surface configured to face towards the vehicle when the armor assembly is mounted thereto, and a second surface opposite thereto. The perforated layer is formed with a plurality of holes each having an opening at least at said second surface. The covering layer is made of a material of a second density which is greater than the first density and is configured to be permanently bent by said explosion into the openings, at opening covering portions of the covering layer, to such a depth as to restrict sliding movement at least between the two layers.

A multi-plate armor system used as an add-on armor in the armored vehicles, especially military vehicles. More specifically, disclosed is an armor system which, having a structure that will not be affected from impacts as well as having weight values acceptable for industry standards per unit area (kg/m.sup.2), at least two plates positioned to the armored vehicle body with a specific distance between them, allows the resulting destructive effect to be felt in the large surface with minimal damage by deflecting the impact direction of the ballistic threat such as bullets, spall etc.

A method of processing ultra high hardness steel is provided to increase its usefulness in armor applications. The method involves slowly cooling the ultra high hardness steel to a cryogenic temperature, slowly returning the steel to an ambient temperature, slowly heating the steel, and again slowly returning it to an ambient temperature.

A steel armor plate and method of manufacturing is described. The armor plate has three curves, a first curve about an axis that parallels the length of the armor plate, and two additional curves about axes that parallel the width of the armor plate. A die for manufacturing said plate is described, the die being formed of a stack of metal plates, each plate having a curve that substantially matches the first curve, the stack of plates being arranged in a step-down-then-step-up fashion to form a concavity that approximates one of the two additional curves.

A method for producing an armor plating for protected vehicles is described. The method employs the following steps: supplying a substrate made of a metal and/or a nonmetal and coating the substrate with the aid of a thermal spraying process. A device for producing an armor plating is also described herein.

A rolling door slat designed to deflect, redirect or absorb severe force is disclosed. The present invention utilizes a double slat design with layered joints, and an open volume enclosing a reinforced core. The reinforced core of the present invention consists of either a solid block of dense, protective material, or layers of material. The layers of material serve to both deflect and absorb impact and blast force, resist vertical force, as well as provide more traditional rolling door functions such as fire resistance or sound and heat insulation.

A composite armor plate is disclosed. The composite armor plate includes a first layer made from an ultra-high hardness, high strength alloy that is bonded to a second layer made from a high fracture toughness alloy that also may have high strength. The composite armor plate according to the present provides a gradient of strength, hardness, and toughness. The composite armor plate according to the invention may also include third and fourth layers of different alloys that provide combinations of hardness, strength, and fracture toughness that are intermediate of the hardness, strength, and fracture toughness provided by the first and second steel layers. A method of making the composite armor plate is also disclosed.

A bullet-resistant garage door is formed with multiple garage door panels spaced vertically and pivotable relative to one another to permit conventional opening of the garage door. Each garage door panel is formed with an interior ballistic panel, an exterior ballistic panel and an insulation panel positioned between the interior and exterior ballistic panels. A ballistic shield is attached to the exterior ballistic panel to overlap the gap between the exterior ballistic panels of adjacent garage door panels. The exterior ballistic panel is operable to allow the penetration of a bullet of a given caliber while dissipating the energy of the bullet so that the bullet will not penetrate the interior ballistic panel and become trapped in the insulation panel. Sheeting and trim members can be attached to the exterior ballistic panel and the shield to provide an aesthetically pleasing appearance for the garage door panels while maintaining bullet-resistant characteristics.

Armor plate having a thickness of at least 3 mm and an edge length of at least 20 mm, wherein the armor plate (10) consists of a material made largely of a component selected from the group hard metal, cermet and/or combinations thereof. An armor plate composite comprising at least two layers of armor plates and an armor are provided as well.
