摘要:
A composite armor includes a ceramic substrate defining a frontside opposite a backside, where a thickness is defined extending between the frontside and the backside. A first tension-wrapped thermoplastic composite overwind is wrapped around the ceramic substrate about the frontside and backside. A first portion of the first overwind overlaps a second portion of the first overwind. The first and second portions of the first overwind are fixedly attached to one another utilizing a first localized heating. The first overwind includes a first tensile pretension. A backing is disposed about the backside of the ceramic substrate attached to the first overwind. The ceramic substrate has a higher modulus of elasticity in comparison to the overwind. The first overwind has a higher modulus of elasticity in comparison to the backing.

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.

A shock and impact resistant multilayered composite comprising an outer shatter protection body, and at least one active body along side the shatter protection. At least one highly elastic and tearproof absorption/dissipation body is provided along side the at least one active body, said outer shatter protection body being cured to said at least one active body and said at least one active body being cured to said at least one absorption/dissipation body. The present invention relates as well to a method for fabrication of such a shock and impact resistant multilayered composite.
摘要:
This invention relates to a multifunctional structure for mitigating the effects of explosions and impeding the penetration of projectiles that is also highly effective at supporting structural (i.e. static) loads. By wrapping a tile in multiple layers of high-performance fabric, upon impact by a projectile additional tensile forces are created, aiding in the deceleration of the projectile. With added layers the tensile forces aiding projectile deceleration increase, resulting in a ballistic panel for use in multifunctional structural/armor systems having a lighter weight and greater stopping power than conventional armor systems in addition to functioning as part of a structure for supporting static loads.
摘要:
A composite armor panel and a method for making the armor is disclosed. In one embodiment the armor consists of a plurality of ceramic tiles (21) individually edge-wrapped (52) with fiber or edge-wrap fabric, which are further wrapped with a face-wrap fabric, and encapsulated in a hyperelastic polymer material (31) permeating the fabric and fibers, with a back plate (41) adhered to the encapsulated tiles. In one embodiment the hyperelastic polymer (31) is formed from a MDI-polyester or polyether prepolymer, at lease one long-chain polyester polyol comprising ethylene/butylene adipate diol, at least one short-chain diol comprising 1,4-butanediol, and a tin-based catalyst.

摘要:
An armor panel having an impact face is provided. The armor panel includes at least one rigid absorbing layer and a high-tensile confining layer surrounding the at least one rigid absorbing layer. The at least one rigid absorbing layer can have a plurality of strip-shaped protection elements that are adhered to one another along a plane substantially orthogonal to the impact face. The at least one rigid absorbing layer can be formed of a glass-ceramic material having a coefficient of thermal expansion substantially equal to zero and that, upon impact by a projectile, converts to a dilatant power at least in an area of impact.
