Description

複合材に使用される様々な層は、それらの異なる弾丸抵抗特性および機能のために選択される。例えば、ガラス層は硬いため容易に弾丸を砕き、また高い耐摩耗性を示すが、ガラス層は、また、脆く、それが砕けて貫通する脅威は全てのガラス層に対して誘起し、さらに弾丸の破片を生成する。弾丸の破片は、車両内部の表面上に多数の突起物を生成するおそれがある。生成された弾片（あるいは破片）は、最初の進入物より実際は危険かもしれない。複合サンドイッチの一部として使用されるプラスチック材の層は、透明な防護複合材に柔軟性を導入する手段を提供する。複合材へ１枚またはそれ以上のプラスチック層を追加することによって、透明な防護具の破壊モードが変更し、したがって、それは破砕よりむしろより延びた状態で終わる。アクリル、ポリウレタンおよびポリカーボネートをベースとする材料は、透明な防護具の複合材を生成する際に有用性を有すると示されたプラスチック材である。 The various layers used in the composite are selected for their different bullet resistance properties and functions. For example, although the glass layer is hard, it easily breaks bullets and exhibits high wear resistance, but the glass layer is also brittle and the threat that it breaks and penetrates induces all glass layers, and more bullets Generate debris. Bullet fragments can generate a large number of protrusions on the interior surface of the vehicle. The generated bullets (or debris) may actually be more dangerous than the first entry. The layer of plastic material used as part of the composite sandwich provides a means to introduce flexibility into the transparent protective composite. By adding one or more plastic layers to the composite, the failure mode of the transparent armor is changed, so it ends up in a rather extended state. Acrylic, polyurethane and polycarbonate based materials are plastic materials which have been shown to have utility in producing transparent armor composites.

図１に代表的に示される典型的な実施例に従って、本発明は改善された光学的透過性のある保護具を提供する。光学的透過性のある保護具は、第１の層１１０（つまり、「正面層」は入来する弾丸に最初に接触する表面である）、第２の層１００（つまり、弾丸のエネルギーを消耗するための「運動層」）、および、それらの間に少なくとも部分的に配置された任意的なエラストマー層（つまり、運動層１００の配置に関して正面層１１０を動けなくするために適切に形成された「接合（ボンディング）層」）を具備する。接合層は、高い伸び特性を有する材料、または、運動層１００および正面層１１０と関連する、温度係数の違いによる伸張差を緩和することができる他の適切な材料からなる。接合層が与えられた温度範囲に亘って適切な伸び特性を具備していない場合、第１と第２層が伸縮する場合、接合層は破損するかもしれない。 In accordance with the exemplary embodiment typically shown in FIG. 1, the present invention provides an improved optically transmissive protector. The optically transmissive protector includes a first layer 110 (ie, the “front layer” is the surface that first contacts the incoming bullet), a second layer 100 (ie, depletes the energy of the bullet). And an optional elastomeric layer disposed at least partially between them (ie, suitably formed to immobilize the front layer 110 with respect to the placement of the motion layer 100 ) "Bonding layer"). The bonding layer is made of a material with high elongation characteristics or other suitable material that can mitigate the difference in elongation due to the difference in temperature coefficient associated with the motion layer 100 and the front layer 110. If the bonding layer does not have adequate stretch characteristics over a given temperature range, the bonding layer may break if the first and second layers expand and contract.

別の典型的な実施例に従って、一般に図２に示されているように、例えば、挿嵌された運動層２００，２２０，２４０は、ウレタン２１０，２３０の比較的薄い層が任意に挟み込まれた１／４インチのポリカーボネートからなる。もちろん、重要な利点は光学的透過性のある保護具に由来するのであるが、比較的薄く堅牢な面の層２５０と結合した様々な他の厚さ寸法を有する高分子およびエラストマー層から実質的に構成される。層の寸法は、およそ±５０％まで変更でき、従来の技術に対して著しい特性向上を提供することができる。加えて、正面と運動層の厚み寸法の比は１：２と重要であり、代替でき、結合してまたは連続して使用され、従来の技術に対して実質的な利益を達成する。異なる厚さ比は、特別の脅威または使用環境に対して独自に適合した、異なる保護具特性を生成することがさらに認識されるであろう。 In accordance with another exemplary embodiment, generally as shown in FIG. 2, for example, the inserted motion layers 200, 220, 240 are optionally sandwiched with a relatively thin layer of urethane 210, 230. Made of 1/4 inch polycarbonate. Of course, an important advantage stems from the optically transparent protective device, but is substantially from polymeric and elastomeric layers having various other thickness dimensions combined with a relatively thin and robust surface layer 250. Configured. The layer dimensions can vary up to approximately ± 50% and can provide significant performance improvements over the prior art. In addition, the ratio of the thickness dimension of the front surface to the moving layer is as important as 1: 2 , which can be substituted and used in combination or in succession to achieve substantial benefits over the prior art. It will further be appreciated that different thickness ratios produce different protective equipment characteristics that are uniquely adapted to the particular threat or environment of use.

別の典型的な実施例に従って、例えば、図４に一般に示されるように、第１の層４１０は実質的に連接されている。正面層４１０は、複数のタイル要素４２０で連接され、運動層４００を覆っている。タイル要素４２０は、異なる形状を含み、例えば、個別のタイル（一般に図４に示されるもの）、球形、多面体、シリンダ、および／または、通常の固体を含む。大理石（例えば、球形）は、効率的なタイル要素材料（１０−１２ｌｂｓ／ｆｔ^２の範囲で計算される正味面密度）として実証されるが、しかしながら、板ガラス（１／４インチから１／２インチの厚さ）のモザイクも、１４ｌｂｓ／ｆｔ^２の範囲の密度でそれ自身極めて効率的であることを実証する。様々なタイル４２０は、任意の適切な高分子マトリクスと共に結合されてもよいが、しかしながら、いくつかの応用では、重要な考察として、光学的透過性のあるタイル要素４２０の屈折率を高分子マトリクスの屈折率と適合させることを含み、それにより、光学的歪みを除去し、さもなければ減少させることができる。 In accordance with another exemplary embodiment, the first layer 410 is substantially articulated, for example, as generally shown in FIG. The front layer 410 is connected by a plurality of tile elements 420 and covers the motion layer 400 . The tile elements 420 include different shapes, such as individual tiles (generally shown in FIG. 4), spheres, polyhedra, cylinders, and / or regular solids. Marble (eg, spherical) has been demonstrated as an efficient tile element material (net surface density calculated in the range of 10-12 lbs / ft ² ), however, flat glass (1/4 inch to 1/2 inch) (Thickness of) also demonstrates itself to be very efficient at densities in the range of 14 lbs / ft ² . The various tiles 420 may be combined with any suitable polymer matrix; however, in some applications, an important consideration is that the refractive index of the optically transmissive tile element 420 is the polymer matrix. Matching the refractive index of the optical fiber, thereby removing optical distortions or otherwise reducing them.

別の典型的な実施例に従って、例えば、図６に一般に示されるように、正面は、ガラス材料６１０，６３０，６４０の１を越える層からなっていてもよく、運動層６００を覆っている。積層する正面層６３０は、連接された層６１０，６２０のタイル要素間における隙間の領域に汚れ、および／または、他の物質が留まるのを妨げるかそうでなければ妨害するために実質的に接触していればよい。タイル要素は、異なる形状を含み、例えば、個別のタイル（一般に図４に示されるもの）、球形、多面体、シリンダ、および／または、通常の固体を含む。図６に示された代表的な実施例では、ガラス正面６１０，６２０の連接されたタイル要素間の境界端部は、実質的にオーバラップするように適切に形成される。このような構成は、光学的な透明性が最大限にされ、特にタイル要素間（上に積層した層および下に積層した層と同様に）の屈折率がよく一致する特殊の応用における特定の利用に適するかもしれない。 According to another exemplary embodiment, for example, as shown generally in FIG. 6, front, it is made of a layer over the first glass material 610,630,640 rather good, covers the movement layer 600 . The laminating front layer 630 is substantially contacted to prevent or otherwise prevent soiling and / or other materials from staying in the area of the gap between the tile elements of the connected layers 610, 620. If you do. Tile elements include different shapes, such as individual tiles (generally shown in FIG. 4), spheres, polyhedra, cylinders, and / or conventional solids. In the exemplary embodiment shown in FIG. 6, the boundary edges between the connected tile elements of the glass fronts 610, 620 are suitably formed to substantially overlap. Such a configuration maximizes optical transparency and is particularly useful in specific applications where the refractive index between the tile elements (as well as the top and bottom layers) matches well. May be suitable for use.
