<p>An assembly useful for constructing protective armor includes a plurality of protective cards suspended in a parallel, louvered relationship between inner and outer mesh layers, thereby permitting air to flow through the assembly while providing a continuous barrier against projectiles approaching from most directions. In some embodiments, the outer mesh layer resists penetration and tends to compress the cards together when struck, causing the cards intercept a projectile that would otherwise pass therebetween. The mesh layers can be para aramid. The mesh can have an open area of 25%, and/or can include leno looper construction. The cards can include thermally pressed and flexed laminated UHMWPE. The mesh yarn can have a denier of 1000 or even 1500, and a stabilizing and/or UV-resistant coating can be included on the outer mesh layer. A plurality of interior card layers can be included, and the assembly can be fire retardant.</p> |
