The present invention provides for methods and compositions for lightweight composite antiballistic assemblies comprising interlocking ceramic plates or modules. The modules may he self-contained and include both ceramic and ductile elements. Alternatively, interlocking ceramic plates may be arrayed over a ductile backing layer of metal or antiballistic fiber or polymer. The ceramic elements may be enhanced with carbon nanotubes or other reinforcing nanomaterials. In one or more embodiments, the strike-face, or front-facing surface, of this assembly may feature a non-planar design to assist in defeating incoming projectiles.

Embodiments disclosed herein are directed to selectively stiffenable assemblies, protective garments and systems that include such selectively stiffenable assemblies for protecting one or more body portions of an individual wearing the protective garment.

A ballistic armored component attaches to the existing retention straps of common combat helmets and provides protection to the otherwise exposed lower skull and upper neck region. A fabric covering contains a soft armor or hard armor insert, and is mounted by straps or other fasteners to existing straps found in conventional helmets. The armor component may be fabric of aramid fibers, or fabric of ultra high molecular weight polyethylene fibers, or may be fabricated of a rigid plate of ceramic, polymer, or metal. The armored component adds additional protection from ground-level or subterranean munitions, by placing a ballistic shape on the lower skull region (occipital region), providing significant additional ballistic coverage with minimal weight and bulk. The fabric shell may also be connected directly to the helmet shell, to allow the component to withdraw within the helmet when the wearer's neck is flexed rearwardly.

Energy distribution structures provide architectural flexibility in various configurations, materials, and scalability, which enables a vast number of applications. An energy distribution structure or array thereof may include a three-dimensional outer component and a three-dimensional inner component within the outer component. The outer component absorbs and redirects initial energy from an applied energy event, and the inner component absorbs and redirects residual energy from the applied energy event. Such an applied energy event may be caused by a ballistic or non-ballistic impact, an instantaneous or prolonged impact such as atmospheric pressure or decompression, explosive overpressure (shockwave), low-velocity contact, and blunt force trauma. Energy distribution structures can increase the strength, resilience or survivability of such events, and reduce the injury or damage to target objects such as people, vehicles, structures, vessels and surfaces by shielding same from such events.

Disclosed herein are embodiments of a releasably engagable system of ballistic-resistant panels including a first ballistic-resistant panel comprising a ceramic plate system, the first ballistic-resistant panel having opposing first ballistic-resistant panel front and back surfaces; and a second ballistic-resistant panel having opposing second ballistic-resistant panel front and back surfaces. Additionally, the embodiments of the releasably engagable systems of ballistic-resistant panels include at least one of fasteners, an adhesive coating, or a securement element, all of which function to releasably engage the second ballistic-resistant panel front surface with the first ballistic-resistant panel back surface in fixed adjacent relation to provide releasably engaged ballistic-resistant panels.

A textile fabric made from aramid fibers finished with a finishing agent. The finishing agent includes a carbonic acid polyester. The textile fabric can be incorporated into a penetration-resistant article. The penetration-resistant article can be a fragment protection mat, a bullet-proof vest, a flak jacket, a stab-resistant vest, or a combination thereof.

Hard armor plate pouches incorporated in a ballistic vest carrier cover that has armor panel pockets with side openings and waist panels. The pouches are attached to the carrier cover outer layer inside the armor pockets with access through the outer layer. In one configuration, the pouch is a single fabric sheet attached to the outer layer around the sheet perimeter. In another configuration, the pouch is a bag that hangs freely in the pocket. The pouch is accessed via a lateral opening or a vertical opening in the outer layer that is closed by an openable fastener, such as a zipper, hook and loop fastener, or snaps. The vertical opening can be hidden behind a placket. Optionally, the waist panels have side pouches that have openings at the side or the top.
