An impact-absorbing article includes two outer panels that sandwich a fiber-composite post-and-sheet layer. The post-and-sheet layer includes a plurality of fiber-composite “posts” that extend orthogonally with respect to a base.

A ballistic-resistant barrier assembly including an elongated barrier having a vertical portion including a substantially horizontal elongated top edge, and a ballistic-resistant device having a first ballistic-resistant panel including an elongated top edge, and an engagement portion affixed to the elongated top edge of the first ballistic-resistant panel, wherein the engagement portion of the ballistic-resistant device is disposed adjacent the elongated top edge of the barrier so that the first ballistic-resistant panel is disposed in a vertical orientation adjacent the vertical portion of the barrier.

An outboard engine ballistic protection system is provided that can be adapted for use with existing small water craft outboard motors. A mounting band circumscribes and is affixed to the power head cowling. The mounting band may be formed of a pair of symmetrically affixed band straps that may be impinged about the cowling and secured fore and aft via a fastening mechanism. Laterally extended struts are provided offset from the port, starboard and aft sections of the power head. A panel support is perpendicularly affixed at an outer terminus of each strut. Mounted to the panel supports about an outer perimeter are a port protection panel, a starboard protection panel, and an aft protection panel. Each protection panel forms ballistic barrier system providing low weight, high energy absorbing structures and materials for ballistic protection against projectiles from munitions and/or shrapnel.

A bullet resistant wall system including ballistic paver blocks constructed, configured, and arranged to form a wall having at least two adjacent individual layers. The at least two adjacent individual layers include multiple adjacent rows of the ballistic paver blocks. The ballistic paver blocks are formed from wet ballistic concrete prepared without an addition of a preformed foam or wet ballistic concrete prepared without an addition of a stabilizing agent.

Ballistic resistant composite materials having high positive buoyancy in water are provided. More particularly, provided are foam-free, buoyant composite materials fabricated using dry processing techniques. The materials comprise fibrous plies that are partially coated with a particulate binder that is thermopressed to transform a portion of the binder into raised, discontinuous patches bonded to fiber/tape surfaces, while another portion of the particulate binder remains on the fibers/tapes as unmelted particles. The presence of the unmelted binder particles maintains empty spaces within the composite materials which increases the positive buoyancy of the composites in water.

A hybrid-layered apparatus for a bulletproof structure includes a viscous absorber layer, a first elastic layer, a viscous-elastic foundation layer, and a second elastic layer, orderly arranged in a lamination manner The viscous absorber layer contains a semi-liquid viscous material. The first elastic layer, laminated fixedly to the viscous absorber layer, has a first predetermined toughness. The viscous-elastic foundation layer, laminated fixedly to the first elastic layer by opposing the viscous absorber layer, has predetermined elasticity and compressibility. The second elastic layer, laminated fixedly to the viscous-elastic foundation layer by opposing the first elastic layer, has a second predetermined toughness. In addition, the first predetermined toughness is higher than the second predetermined toughness.

A tile to be used in an arrangement of identical tiles of an armor, the tile including an obverse face, a reverse face opposite the obverse face, and an endless edge between the obverse face and the reverse face, the endless edge being defined by a plurality of peripheral boundaries connected by curved sections, wherein the obverse face includes a first region and a second region each configured to be overlapped by a corresponding region of a reverse face of another tile, and a strike face region that is not overlapped by another tile, the first region and the second region being adjacent to the non-overlapped strike face region, the strike face region including a Y-shaped raised portion and no other raised portion or recessed portion, and the reverse face including a Y-shaped depression at a location corresponding to the location of the Y-shaped raised portion, and no other depression or raised portion.

A multi-threat security apparatus system for critical infrastructure protection is disclosed having an above-ground concrete base, a vertical post system adapted to be attached to the above-ground concrete base and to receive a plurality of louvers. The plurality of louvers provides the necessary ballistic protection for and air flow through to the critical infrastructure. The louvers may include a composite of aluminum foam, a resin impregnated ballistic material and an aluminum foam. The composite structure may be used on doors, panels or building walls.

Energy dampening and/or dispersing systems may include a gel member having a top surface and a bottom surface, an aerated gel member having a top surface and a bottom surface, and the top surface of the aerated gel member secured to the bottom surface of the gel member. In some embodiments, the energy dampening and/or dispersing systems may include a support structure secured to the gel member, and a cover extending over the top surface of the support structure and the bottom surface of the aerated gel member. The energy dampening and/or dispersing systems may be operable in ballistic garments, footwear, sporting goods, and vehicles.

An armor plate consists of a material comprising a cermet, and the armor plate has a density in the range from 5.0 to 6.5 g/cm.sup.3. An armor plate composite and an armor are provided as well.
