A bulletproof vest assembly for enhancing comfort of a ballistic vest for a female user includes a ballistic vest is comprised of a penetration resistant material to protect a user from being injured by a projectile. A ballistic plate is insertable into the ballistic vest and the ballistic plate is comprised of a bullet resistant material to inhibit bullets from penetrating the ballistic plate and injuring the user. Furthermore, the ballistic plate has a concave section to accommodate breasts of a female user thereby enhancing comfort for the female user.

A ballistic tile for use in an imbricated pattern of like ballistic tiles to achieve coverage of a protected area by the imbricated pattern, while having rounded corners to limit the potential for spalling on ballistic impact. The ballistic tile may include a strike face that is generally undulating to laterally deflect at least a portion of the impact force, and to induce turning of the ballistic projectile on impact to further distribute the impact force. The ballistic tile may also include one or more features on an obverse and reverse side thereof that, when arranged in an imbricated pattern, limit lateral motion of the tiles on ballistic impact, and/or laterally transmit the energy of the projectile for deflection and absorption thereof.

A multi-plate armor system used as an add-on armor in the armored vehicles, especially military vehicles. More specifically, disclosed is an armor system which, having a structure that will not be affected from impacts as well as having weight values acceptable for industry standards per unit area (kg/m.sup.2), at least two plates positioned to the armored vehicle body with a specific distance between them, allows the resulting destructive effect to be felt in the large surface with minimal damage by deflecting the impact direction of the ballistic threat such as bullets, spall etc.

A slat arrangement for redirecting the trajectory of a bullet has a plurality of elongated steel slats, and each elongated steel slat has a longitudinal front edge and a longitudinal back edge stretching between a first end and a second end. The steel slats are positioned in a louver-like fashion for changing the direction of a bullet following a trajectory along the normal of the slat arrangement. A support structure is connected to each steel slat at the back edge of the steel slat, between the first end and the second end of the steel slat.

An ablative composite material including a matrix and a reinforcement, characterised in that: the matrix is a phenolic resin or an epoxy resin and the reinforcement is formed of short carbon fibres with a length of between 0.5 mm and 20 mm, and a diameter of between 6 μm and 20 μm.

A steel armor plate and method of manufacturing is described. The armor plate has three curves, a first curve about an axis that parallels the length of the armor plate, and two additional curves about axes that parallel the width of the armor plate. A die for manufacturing said plate is described, the die being formed of a stack of metal plates, each plate having a curve that substantially matches the first curve, the stack of plates being arranged in a step-down-then-step-up fashion to form a concavity that approximates one of the two additional curves.

Vehicle armor may include an assembly of components including an outer armor pack, an air gap, an inner armor pack, and a high energy absorbing layer. At least one version of the outer armor pack may include an outermost outer fiber reinforced composite protective layer of ≧1 mm thickness, an outer ceramic armor layer, and an inner fiber reinforced composite support layer to absorb residual energy from small arms. The air gap may be between 1-10 mm to allow for deflection of the outer armor pack. The inner armor pack may include an outer fiber reinforced composite protective layer of ≧0.5 mm thickness, an inner segmented ceramic armor layer, and an innermost inner fiber reinforced composite layer of ≧10 mm thickness. The high energy absorbing layer may have ≧25 mm thickness and be configured to mitigate the effect of residual fragments defeating the outer and inner armor packs.

A compact antenna for centimetric frequency bands includes an active planar element forming a radiator, coupled to an input of a receiver circuit and/or to the output of an emitter circuit, and a passive planar element forming a reflector. The passive planar element is formed by a periodic structure of the metamaterial type comprising a network of resonating cells, in particular cells of the complementary concentric slit-ring type Complementary Split-Ring Resonator (CSRR). A clip-shaped support made of a dielectric material supports the active planar element and the passive planar element.
