A pre-stressed curved plate comprising a curved plate having at least one concave surface, the curved plate being enveloped and adhesively bonded with tensioned reinforcing fibers, whereby the reinforcing fibers are first wound around the plate under tension being spaced apart from the concave surface and subsequently subjected to pressure to stretch and bond the reinforcing fibers to the surfaces of the plate, where upon bonding, the tensile strain of the fiber introduces stress in the plate.

An armor production tool including a housing having at least two housing portions that form a substantially air-tight chamber when closed. The tool can include a lower thermal diaphragm forming at least a portion of a mold, and an upper thermal diaphragm forming at least a portion of the mold and capable of engaging the lower flexible membrane. The thermal diaphragms may comprise a thermal transfer membrane, a pressure bearing membrane and a fluid dispersion layer between the thermal transfer membrane and the pressure bearing member. A heating or cooling fluid can be circulated through the fluid dispersion layer to apply heat or to cool the armor part during the molding process. The tool can include a pressure port for pressurizing the chamber and to move the thermal diaphragm towards each other to apply compression on the molded armor part, and a locking mechanism for locking the two housing portions.

Embodiments of the present invention relate to composite materials. In one embodiment, a composite material comprises an inorganic ceramic matrix comprising a first surface and a second surface opposite the first outer surface and generally parallel to the first outer surface. At least one open weave fiber glass fabric is disposed in the inorganic ceramic matrix between the first surface and the second surface. In another embodiment, a composite material comprises a first inorganic ceramic matrix comprising pieces of stone, a second inorganic ceramic matrix attached adjacent to the first inorganic ceramic matrix, and at least one open weave fiber glass fabric disposed in the second inorganic ceramic matrix.

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.

Multi-impact multi-layer body armor is presented. A first layer is a single layer of front covering material. A second layer, is a ballistic ceramic plate formed of a plurality of curved smaller ceramic tiles that are bonded together using a structural adhesive. A third layer formed of one or a plurality of aramid layers such as Kevlar XP. A fourth layer formed of a rigid backing plate, formed of ultra-high molecular weight polyethylene such as Spectra Shield. A fifth layer is a single layer of rear covering material. Thus, an improved body armor is presented which is inexpensive to produce, light, durable and can sustain multiple impacts.

Embodiments of the invention provide body armor composite and methods of fabrication. The body armor composite can include at least one strike-face layer, at least one strike-face reinforcement layer, and at least one catchment layer. Some embodiments include body armor composite with a bump guard layer, and a back-face reduction layer. In some embodiments, the fabrication method includes bonding multiple layers to form an armor composite. Some embodiments include an armor production tool including a housing at least two housing portions which form a substantially air-tight chamber when closed. The tool can include a lower flexible membrane forming at least a portion of a mold, and an upper flexible membrane capable of engaging the lower flexible membrane. The tool can include a pressure port for pressurizing the chamber and to move portions of the mold towards each other, and a locking mechanism for locking the two housing portions.

A process of bonding different constituent materials of different tensile strengths in a single step in an isostatic high pressure reactor in order to produce a composite material.

A structure may comprise a first outer layer and a polymer fiber composite layer mounted on one side of the first outer layer.

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 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.
