Armor plating made of fine-grain boron carbide and silicon carbide
An antiballistic armor-plating component, includes a ceramic body made of a material comprising, as percentages by volume, between 35% and 55% of silicon carbide, between 20% and 50% of boron carbide, between 15% and 35% of a metallic silicon phase or of a metallic phase including silicon.
Combined armor plate
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.
Safe equipment protecting soldiers or people from bullets and shrapnel
This invention makes a carriable equipment protecting soldiers or people against bullets from guns or shrapnel from explosive exploding. Many soldiers were killed or injured in a war. Many people were killed or injured by gun shootings in U.S. Bulletproof material with high stiffness and tensile strength, e.g., high strength fabrics, carbon fabrics, bulletproof steel, ceramics, glasses and alloy, has been developed with new technology. Multi-layers of high strength fabrics or carbon fabrics or a plate of bulletproof material is hard to be penetrated by a flying bullet or shrapnel, but existing bulletproof hats or clothes only has partial protecting effect. If the canopy of an umbrella is made of bulletproof fabrics or carbon fabrics or plates of bulletproof material, this umbrella can fully protect soldiers or people behind the umbrella canopy from bullets or shrapnel.
Compact rifle protection ballistic shield
A rollable armor panel, and a rollable ballistic shield that includes the rollable armor panel is described. The rollable armor panel includes an adhesive-coated first ballistic fabric, a plurality of ballistic tiles arranged on and attached to one side of the first ballistic fabric, and a lattice arrangement of adhesive-coated ballistic fabric attached to the ballistic tiles and located opposite to the one side, the lattice having openings over the ballistic tiles, the armor panel being flexible enough to permit rolling of the armor panel into a rolled state. In order to facilitate rolling, the fabric lattice on the rear side of the imbricated array of wrapped ceramic tiles permits lifting of one side of a tile relative to another along the rolling direction. Further, the fabric-encapsulated wrapped imbricated ceramic is attached to a ballistic fabric backer in such a way that layers can slide over each other during rolling and unrolling. Attachment points of the various components of the armor are designed to return those components into alignment when the shield is deployed flat from its rolled state.
ENERGY DISSIPATION PLATE FOR ARMOR COMPRISING A FIBROUS POROUS DAMPING MATERIAL
An impact energy dissipation plate for anti-ballistic armor, the dissipation plate including a damping material including a fibrous reinforcement bonded by an organic matrix including a thermosetting resin, the reinforcement including inorganic fibers assembled in the form of yarns, the damping material having the following features the volume fraction of fibrous reinforcement of the damping material is between 20% and 70%, the remainder to 100% including the matrix and porosity; the fibrous reinforcement includes at least 50% by volume of silica fiber yarns of which SiO.sub.2 content by mass of more than 90%, and the porosity of the damping material is between 2% and 10% by volume.
