The invention relates to a ballistic layer for a ballistic multilayer arrangement (1), wherein it is formed by an absorption layer (2, 2a, 2b) that entirely or largely comprises expanded glass (21) and by a ballistic multilayer arrangement (1) with an impact side (A) and a back side (B), wherein at least one of the layers is formed by such an absorption layer (2, 2a, 2b) that entirely or largely comprises expanded glass (21).

The invention relates to a method for producing a body armor with several armor elements (4) that are connected to one another, wherein the method comprises the following steps: a) supply of an armor blank (2) with at least two armor elements (4) which are connected to one another or in a fixed position relative to one another, b) reshaping of the armor blank (2) in at least one reshaping direction such that the at least two armor elements (4) are reshaped, c) separation of the at least two connected armor elements (4) from one another and d) flexible connection of the separated armor elements (4).

According to an embodiment of the present invention, a three-dimensional architected armor structure includes a core structure and a matrix. The core structure includes: a plurality of impact members; a plurality of joint members below the impact members; and a plurality of connection members respectively extending between one of the impact members and one of the joint members. The matrix fills at least a portion of a space between the impact members, the joint members, and the connection members.

A carrier system that includes a multi-curve front body armor plate that is wearable on a front torso having a protruding chest. The strike face has a lower region with a lower convex portion shaped to follow a cylindrical contour of an abdomen and chest of the torso. An upper portion of the strike face laterally tapers to a top edge and curves backwardly to accommodate the protruding chest. An armor carrier of the carrier system includes (i) a back panel; (ii) a front panel having an opening that is sized to receive the multi-curve front body armor plate; and (iii) a shoulder harness connecting the front and back panels. The shoulder harness providing a support surface that rests upon shoulders of a wearer.

An armored plate assembly can include a base plate, a gap layer, a containment structure around edges of the gap layer, and a coating that can be applied to an assembly of the base plate, the gap layer, and the containment structure. In some embodiments, the base plate can be formed from steel, the gap layer can be formed from natural cork, the containment structure can be formed from a polymer, and the coating can be formed from polyurea.

An impact absorption structure (1) is provided. The impact absorption structure (1) comprises an impact receiving component (3), capable of, after receiving an initial impact shockwave, separating that shockwave into at least a first shockwave (S11) and a second shockwave (S122), time-spaced from the first shockwave (S11). The impact absorption structure (1) also comprises an energy dissipation component (5) adjacent to the impact receiving component (3), such that the time-spaced shockwaves (S11, S122) can be passed across an interface from the impact receiving component (3) to the energy dissipation component (5). The energy dissipation component (5) comprises a chemical element or compound such as calcite exhibiting a first displacive phase change from a first phase to a second phase (52) upon experiencing the first shockwave (S11), a second displacive phase from the second phase (52) to a third phase (53) upon experiencing the second, later shockwave (S122), and a third displacive phase change from the third, or a later, phase (53) to the first phase upon unloading after the second shockwave (S122), the compound thereby exhibiting a hysteresis cycle in which elastic energy is dissipated.

In one aspect, an armor plate (10) with a thickness of at least 2 mm and an edge length of at least 20 mm is described, wherein the armor plate (10) consists of a material that contains tungsten heavy metal or tungsten carbide as the essential component.

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.

Body armor composite material that includes a substrate, a tempered aluminum binder, and ceramic spheres embedded in the binder. The ceramic spheres have interstitial space that are filled by the aluminum binder.

A system and device for providing bullet proof protection to persons is described. A pre-staged shield, possibly wall mounted, that is capable of shielding the head and torso, for example, may be provided in a vulnerable facility. An optional and distinct alert system may be activated when the shield is removed from its location, whether seated on the wall, mount, or container such as a storage locker. Such alert system may be triggered by a switch, such as a pressure sensing seat in communication with a loudspeaker and alarm or monitoring system. When an alarm is activated, an optional distinct alert is sounded within the facility and the monitoring system may alert law enforcement and emergency first responders of the active shooter location. Such a shield and system may permit an unarmed, unprepared person to have the opportunity to shield themselves.
