20110203452 | ARMOR PLATE - An armor plate includes at least four layers configured to generate a compression wave that is dissipated in a fracture player. The armor plate includes a deformable layer of a material having an elongation before failure of 20% or more; a transparent ceramic layer adjacent the deformable layer; a transparent fracture layer adjacent the ceramic layer; and a transparent spall liner backing the fracture layer. | 08-25-2011 |
20120312150 | Body armor of ceramic ball embedded polymer - A body armor composite material is provided to protect a wearer from small-arms projectiles. The material includes a flexible liner, a polymer binder disposed on the liner, and ceramic solids embedded in the binder. The flexible liner conforms to a portion of the wearer and elastically deforms in response to application of mechanical force. The binder can be a polyurea foam. The solids can be spheres arranged in a single-layer pattern substantially parallel to liner. | 12-13-2012 |
20140066236 | Airbag projectile for impeding surface vessel - A projectile can be fired at a surface vessel and, upon impact, an air bag may be deployed almost instantaneously from underneath the vessel. Through the rapid inflation of the air bag, the stability and orientation of the target surface vessel may be disturbed. Disturbance, at a minimum, may reduce and change the trajectory of the surface vessel, but, in some circumstances, the surface vessel may be overturned. The air bag may be designed with an anti-slip coating to directly couple to the wet hull of the surface vessel. In some embodiments, the projectile may include a delay to enable the air bag to be positioned under the vessel before inflation thereof. | 03-06-2014 |
20150061182 | Method for forming cylindrical armor elements - Methods for forming armored glass cylinders suitable for improving resistance of armor to armor piercing rounds, explosively formed penetrators, or other threats. Cool a cylindrical glass or ceramic element to a temperature below that of a cylindrical casing, place the cylindrical glass or ceramic element into the cylindrical casing while the cylindrical glass or ceramic element is cool, and seal the cylindrical casing and allow the temperature of the cylindrical glass or ceramic element to rise, such that the cylindrical casing compresses the cylindrical glass or ceramic element. Alternately, heat a metal cylindrical casing, press glass or ceramic into the cylinder while the metal cylinder is at an elevated temperature, seal the metal cylindrical casing while metal cylindrical casinger is at an elevated temperature, and allow the the metal cylinder to cool, such that when cooled, the cylindrical casing will compress the glass in all directions. | 03-05-2015 |
20150147545 | ELASTOMERIC BILAYER ARMOR INCORPORATING SURFACE-HARDENED SUBSTRATES - An armor system is formed of a substrate including an underlying substrate layer of less hard material and including a thin layer of harder material at a first face of the substrate, and an elastomeric material layer positioned at the first face of the substrate. The increased hardness of the thin hard layer increases the penetration resistance of the armor by increasing the elastomer's contribution to penetration resistance. The properties of the substrate can be independently selected, allowing the use of substrates with lower hardness, increasing the armor's ballistic performance, and lowering the weight of the armor. | 05-28-2015 |
20150377592 | Polymer Coatings with Embedded Hollow Spheres for Armor for Blast and Ballistic Mitigation - A lightweight armor system providing blast protection and ballistic protection against small arms fire, suitable for use in helmets, personnel or vehicle protection, and other armor systems. A hard substrate is coated on the front surface with a thin elastomeric polymer layer, in which hollow ceramic or metal spheres are encapsulated. The coating layer having a thin elastomeric polymer layer with encapsulated metal or ceramic hollow spheres can be stand-alone blast protection, or can be added to an underlying structure. The glass transition temperature of the polymer is preferably between negative fifty Celsius and zero Celsius. | 12-31-2015 |
20160003582 | Polymer Coatings for Enhanced and Field-Repairable Transparent Armor - A coating of atactic polypropylene over a transparent armor substrate improves resistance to penetration while allowing convenient repair of minor abrasions and scratches. | 01-07-2016 |
