A bulletproof protection elementary component of the tile type comprises a prism-shaped body having a first face and a second face of greater extension, which are opposite each other, and a side surface having a first height, at least one raised section from the first face by a second height, wherein the raised section is prism-shaped and has a base area which is less than an area of the first face. A ballistic panel and a bulletproof protection structure and a bulletproof vest, comprising a plurality of the elementary components, are also herein described.

A composite material (10) comprising: a base layer (48); a plurality of protective plates (41, 51, 51a, 51b) located on the base layer (48); an attaching means (43) to connect the base layer (48) to the protective plates (41),
wherein
the attaching means (43) is positioned along a first direction (46) on the base layer (48) to resist pivoting of each protective plate (41, 51, 51a, 51b) about an axis normal to the base layer (48).

The present invention relates to a flexible ballistic armor apparatus for deflecting high velocity firearm, fragmentation, or shrapnel projectiles with a flexible armor unit. The apparatus minimizes the deterioration of the armor when subjected to shock waves or shear forces of a ballistic impact. The present invention also relates to the use of a flexible armor unit with soft body armor, a vehicle, a vessel, an aircraft or in structural applications.

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 frustum embedded fabricated composite protective structure is provided, including a restraint frame, a back plate, an infill block and a buffer block. The restraint frame is provided with a plurality of mounting holes matching with the shape of the infill block, the restraint frame is arranged on the back plate, the infill block is in a frustum shape. The buffer block and the infill block are installed in the mounting hole of the restraint frame, the buffer block is arranged on the smaller end of the infill block, and the infill block is wedged into the mounting hole of the restraint frame through a wedge surface mating. Because this protective structure is assembled by multiple restraint frames and infill blocks, under the prestress restraint of partition blocks, the damage range after penetration or explosion will be significantly reduced, and it can withstand multiple blows.

A ballistic material utilizes a three-dimensional, square-based pyramid unit cell (SBPUC) sphere structure that includes four base spheres and a primary sphere, which are tightly packed and in contact with each other. The base spheres and the primary sphere are arranged whereby the centers of each of the base spheres form corners of a square base, while the center of the primary sphere forms an apex, which when connected to the corners, forms an imaginary pyramid. The ballistic material is formed from one or more layers of SBPUCs that are provided between a pair of spaced substrate layers, so as to achieve the desired level of ballistic protection performance.

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.

An armor system that includes a first armor article that includes a plurality of energy-dispersion objects arranged in a predetermined configuration, wherein the plurality of energy-dispersion objects includes a plurality of hollow objects, and wherein at least some of the plurality of hollow objects are filled with an inner filler material; and a lock mechanism configured to hold the plurality of energy-dispersion objects in the predetermined configuration. A method for manufacturing an armor system, the armor system including a first armor article, the method including producing a plurality of hollow hemispheres; affixing pairs of the plurality of hemispheres to one another to form a first plurality of spheres; treating each one of the plurality of hemispheres with an anti-ballistic treatment; inserting a filler material into each one of the plurality of hemispheres; and locking the first plurality of spheres into a predetermined configuration.

A composite material comprising an elastomer having ceramic platelets dispersed therein, and applications thereof including an armour system. The ceramic platelets each have a first plate surface and a second plate surface, the first and second plate surfaces being separated by a height H. The ceramic platelets each having a maximum diameter D measured in the first and second plate surfaces. The ceramic platelets have a mean height H.sub.m and a mean maximum diameter D.sub.m. The mean height H.sub.m is 0.1 to 1 μm and the ratio D.sub.m:Hm is 20 or more.

Armor systems are described. Armor systems include an armor that includes a container, in which the container includes a bottom, a top and sides and is enclosed, hollow spheres that are placed in a stack in the container, explosive that is wrapped around each of the hollow spheres in the container, in which the explosive-wrapped spheres substantially fill the container.
