A protective assembly comprises a first region formulated and configured to provide protection from alpha, beta, and electromagnetic radiation and comprising a composite of particles and polymer; a second region formulated and configured to provide protection from ballistic impact and comprising a composite of fibers and polymer; and a third region formulated and configured to provide protection from thermal radiation and comprising a composite of particles, fiber, and polymer. The protective assembly may be provided on an aerospace structure. The protective assembly may be formed on the aerospace structure body using a co-curing process.

An armor plate is provided having a lamination of an embedded reinforcement basalt fiber mesh within a laminated cast metal alloy; and at least two layers of an aramid fiber. A process to make the armor plate can include suspending a basalt weave within a mold; heating aluminum 6061 or 7075 alloy to a molten state; pouring the molten aluminum into the mold; cooling the resultant matrixed aluminum to ambient temperature; and laminating at least two layers of ballistic fiber to the matrixed aluminum.

Garments made from a composite, protective fabric are disclosed. The composite fabric has textile layers placed in proximity to metallic mesh layers of woven stainless steel mesh. The metal mesh layers formed from any metal which forms suitable fibers. The textile layers are fabric formed with well-known fabric fibers selected from those including para-aramid fibers, meta-aramid fibers, ultra-high molecular weight polyethylene fibers, polyethylene terephthalate fibers, cellulose fibers, polyamide fibers, a mixture of para-aramid fibers and meta-aramid fibers, and a mixture of para-aramid fibers and carbon fibers. Forming the non-metal textile layers is by any suitable method for interlacing yarns including weaving, knitting, crocheting, knotting, or felting, or combinations thereof. The garments made using the fabric include gloves, bullet proof vests and chain-saw resistant trousers.

Armor plating is provided for armored land vehicles or watercraft, the armor having a base armor plate and an additional armor plate fixed thereto on the enemy side, such that it can be removed. A structural component can be used as a base armor plate for such vehicles, and comprises a layered structure with a core composite having an inner honeycomb core and at least one covering layer. The layered structure does not contain supporting metal layers or ceramic, hard material layers. Another essential characteristic is the use of fixture elements which are anchored in the core composite to allow additional armor plating to be detachably fixed on the enemy side. The core composite therefore essentially offers basic protection itself, while also acting as the carrier structure for interchangeable additional armor plating.

High tenacity, high elongation multi-filament polymeric tapes as well as ballistic resistant fabrics, composites and articles made therefrom. The tapes are fabricated from multi-filament fibers/yarns that are twisted together, bonded together, compressed and flattened.

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.

Multilayered bulletproof device including a first layer external during use, provided with a first surface external during use, suitable to receive firearm bullets, a second surface internal during use, a second layer internal during use, disposed facing the second surface of the first layer and defined by a plurality of fibers, where the first layer is made of metal material and the first surface of the first layer is provided with a plurality of protruding portions distributed uniformly, one adjacent to the other, on the first surface.

Composite door systems that are configured for providing safety, security, and resistance to physical impacts or threats (natural and man-caused), and which can be utilized in barrier structures, such as for doors. The composite door systems may include one or more layers, each of which may have one or more fiber layers, such as fabric layers or plastic layers. The composite door systems may further include one or more additional layers of a sheet material, a fill material, or the like. The composite door systems are infinitely customizable and configured to be adapted to a variety of applications, and scalable levels of protection.

A combined armor plate is claimed. The combined armor plate is formed by soft and hard armor plates, the hard armor plate is arranged in a front part, the soft plate is arranged in a rear part. It comprises one or several hard armor plates having a total area smaller than a total area of the soft armor plate. The hard armor plates and the soft armor plate are interconnected such that they form firm and uniform structure in each formed hard ballistic part on each connection area between the soft armor plate and the hard armor plates. Soft ballistic parts have lower firmness and lower thickness of a ballistic material than the combined armor plate in locations of the hard ballistic parts. Technical effect: increasing effective ballistic protection area and resistance of the hard armor plate and the soft armor plate to penetration and blunt trauma effect.
