Anti-ballistic systems and methods for making same are described. The anti-ballistic systems may be formed from various materials arranged in a structure, such as a wall structure. For example, an anti-ballistic system may be formed from a metal material, a polymer material, and a stone material. In some embodiments, the metal material may include aluminum (for example, an aluminum composite panel), the polymer material may include ethylene vinyl acetate, and the stone material may include granite. The anti-ballistic wall systems may be configured to be resistant to ballistics, blasts, and/or forced entry.

A method for manufacturing armor includes coating a first side of a ballistics arresting core with a first shell layer to create a partially coated ballistics arresting core, placing the partially coated ballistics arresting core in a vacuum bag and depressurizing the vacuum bag and curing the partially coated ballistics arresting core in the depressurized vacuum bag to create a partially shelled ballistics arresting core. The method further includes removing the partially shelled ballistics arresting core from the vacuum bag, coating a second side of the partially shelled ballistics arresting core with a second shell layer to create a fully coated ballistics arresting core, placing the fully coated ballistics arresting core in a vacuum bag and depressurizing the vacuum bag, and curing the fully coated ballistics arresting core in the depressurized vacuum bag to create a fully shelled ballistics arresting core.

A method includes providing an article having an impact side and an asset side and exposing the impact side of the article to a plurality of pressure waves, the pressure waves having a plurality of pressure wave frequencies. The method also includes reflecting at least one composite harmonic of a portion of the pressure wave frequencies and reducing an amplitude of a portion of the pressure waves.

A rolling door slat designed to deflect, redirect or absorb severe force is disclosed. The present invention utilizes a double slat design with layered joints, and an open volume enclosing a reinforced core. The reinforced core of the present invention consists of either a solid block of dense, protective material, or layers of material. The layers of material serve to both deflect and absorb impact and blast force, resist vertical force, as well as provide more traditional rolling door functions such as fire resistance or sound and heat insulation.

The invention relates to a method for producing a shielding cartridge (1) of a turbomachine element (10), said method comprising a step of winding a carbon wire (3) comprising a plurality of fibres about a longitudinal axis and a step of trapping and preserving the outside surroundings of the wound-up wire (3) in a housing (2).

A multi-layer body armor plate includes a strike plate; a mesh layer positioned over the strike plate, the mesh layer having a number of open cells; and an outer skin layer positioned over the mesh layer so as to encapsulate the open cells of the mesh layer between the strike plate and the outer skin layer. The open cells of the mesh layer may entrap air or may be filled with expandable, buoyant foam.

An armor system or plate designed to reduce the extent of back face deformation by re-directing the pressure wave created by a projectile impact. More specifically, armor systems according to embodiments of the invention are provided with redirection channels whereby the pressure or shock waves generated by projectile impact are guided or spread laterally along the channels and out of the plate so as to reduce back face deformation and consequent impact to the wearer.

A modular armor system configured to be readily attached and detached from a frame surrounding a window in a vehicle or other structure, such as a building. The modular armor system may be configured to provide any desired ballistics protection rating. In one embodiment, the modular armor system includes a ballistics-grade armor panel having an outer strike face and an inner surface opposite the outer strike face. The modular armor system also includes a fastener coupled to the ballistics-grade armor panel. The fastener is configured to detachably couple the ballistics-grade armor panel to the frame surrounding the window in the vehicle or other structure.

A ballistic fiber composition may include a fabric that may be comprised of polyamide fibers, an adhesive polymer coating the fabric, and a carbonaceous material and a ceramic filler embedded in the adhesive polymer coating. A method of producing a ballistic protective article may include mixing a carbonaceous material and a ceramic filler into an adhesive to create a mixture, and then coating a polyamide fabric with the mixture. A ballistic protective article may include an aromatic polyamide fabric that is coated with an elastomeric adhesive polymer coating, with calcium carbonate and a carbonaceous material embedded in the elastomeric adhesive polymer coating. The carbonaceous material may include at least one material selected from graphene, carbon nanofiber, and carbon nanotubes.

A ballistic panel and a ballistic panel assembly that absorb and stops high velocity projectiles is provided. The ballistic panel includes a first layer assembly with a first plurality of weave mesh layers, a second layer assembly with a second plurality of weave mesh layers, and a third solid layer sandwiched between the first layer assembly and the second layer assembly. The ballistic panel assembly can include a releasably attachable GPS tracking chip, an alert signaling device, and/or an outer electromagnetic shield.
