Abstract:
A multi-layer armor plate comprises a strike plate, a structural mesh layer, an outer skin, a compliant mesh layer, and an inner skin layer. The strike plate has an outer surface and an inner surface. The structural mesh layer is positioned on the outer surface of the strike plate and includes lattice structure with a first structural compliance. The outer skin layer is positioned over the structural mesh layer. The compliant mesh layer is positioned on the inner surface and includes lattice structure with a second structural compliance that is greater than the first structural compliance. The inner skin layer is positioned over the compliant mesh layer.
Abstract:
An impact attenuation system comprises an aluminum honeycomb sheet having a top surface and a bottom surface. The aluminum honeycomb sheet defines a plurality of approximately hexagonally shaped cells. The bottom surface defines a single sheet of contiguous cells and the top surface defines two or more islands of contiguous cells separated by one or more slits. At least a portion of one or both of the top surface and bottom surface may be covered by a polymer skin. The polymer skin may comprise carbon fibers and/or fiberglass.
Abstract:
In a method of treating a material solvent, brass granules, copper granules, and carbon nanotubes are mixed, in the absence of silver, iron pyrite, and graphene, to form a first mixture. The first mixture is then added to a second mixture of brass and copper granules. The first and second mixtures are mixed until all of the granules of the second mixture of brass and copper are uniformly saturated with the first mixture, whereafter the second mixture is dried to form a treated material. The treated material can be mixed with one or more metals in a high-temperature crucible and heated until melted to form a metal alloy. Each of the one or more metals can be a ferrous and/or nonferrous metal. The melted metal alloy can be poured into a mold and allowed to cool and harden. The cooled and hardened metal alloy can be formed into a finished form via drawing through a die; continuous casting; or rolling.
Abstract:
The present invention provides an energy absorber for a blast barrier system comprising a substantially tubular member extending longitudinally along an axis from a first end portion to a second end portion, each of the first end portion and the second end portion having a substantially similar geometric, profile, wherein the energy absorber collapses under a predetermined load when compressed by a residual blast force. The energy absorber of the present invention may help minimize damage to people and structures by further dissipating force from a blast in a blast barrier system.
Abstract:
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.
Abstract:
A polyurea hybrid ballistic armor formed from novel cured reaction products of various diamines and polyester diols with isocyanate curing agents. The cured reaction product can absorb large amounts of energy from ballistic projectiles, and when various hard granular particles are embedded within the cured reaction product, a strike plate effect can be realized, allowing the polyurea hybrid ballistic armor to defeat ballistic projectiles. The polyurea hybrid ballistic armor can additionally be utilized to add additional layers of protection to existing armor systems.
Abstract:
Method for manufacturing a multi-layered shaped metal body includes introducing gas into a molten metal in order to form a flowable metal foam, introducing the flowable metal foam into a mold containing therein at least one insert element comprising a freely shearing chain mail of loosely interlinked rings, and cooling the flowable metal foam in the mold to form a shaped metal body.

Abstract:
A modular armor system configured to be readily attached and detached from a frame surrounding a window in a vehicle or other structure, such as a building. The modular armor system may be configured to provide any desired ballistics protection rating. In one embodiment, the modular armor system includes a ballistics-grade armor panel having an outer strike face and an inner surface opposite the outer strike face. The modular armor system also includes a fastener coupled to the ballistics-grade armor panel. The fastener is configured to detachably couple the ballistics-grade armor panel to the frame surrounding the window in the vehicle or other structure.
Abstract:
A light-weight composite material with enhanced structural characteristics includes, in one embodiment, a compositionally modulated nanolaminate coating electrically deposited into an open, accessible void structure of a porous substrate. As a result of including a nanolaminate within the void structure, the composite can include a greater amount of nanolaminate material per unit volume than can be achieved by depositing a nanolaminate material solely on a two-dimensional surface. In addition, the nanolaminate material as well as other material electrodeposited to form the composite is compositionally modulated so that discontinuities between layers are minimized and potentially eliminated. The light-weight but structurally enhanced composite material can be used in a number of different applications including, but not limited to, ballistic applications (e.g., armor panels or tank panels), automotive protection applications (e.g., car door panels, racing shells) and sporting equipment applications (e.g., golf club shafts and tennis racket frames).
