    • A foamed composite armor laminate comprising interleaved combinations of ballistic resistant fabrics, and ceramic and/or metallic plates or sheets in a polymeric foam matrix. The foamed composite armor can be fabricated by inserting polymer powder or sheets between layers of fabric and/or ceramic or metallic sheets to form a laminated structure, heating this laminated structure under pressure to form a consolidated panel, and then foaming the polymeric portion of the consolidated panel in an autoclave or pressure vessel by saturating the polymeric portion with inert gas at elevated temperature, rapidly releasing the pressure and controllably cooling the laminated structure to ambient. Alternatively, pre-foamed panels can be laminated to fabric, ceramic and/or metallic sheets using adhesives or the like. Through proper selection of the various elements of the laminate, i.e. the foamed polymer matrix, the polymeric fabric(s) and the ceramic and metallic sheet(s), a wide variety of ballistic, flame retardance, stiffness and other properties can be custom designed into the product for specific end use applications.
    • 一种发泡复合装甲层压板,其包括防弹织物的交错组合,以及聚合物泡沫基质中​​的陶瓷和/或金属板或片。 可以通过将聚合物粉末或片材在织物和/或陶瓷或金属片材层之间插入以形成层压结构,在压力下加热该层压结构以形成固结的板,然后使聚合物部分发泡 在高压釜或压力容器中通过在高温下用惰性气体饱和聚合物部分,快速释放压力并可控制地将层压结构冷却至环境。 或者,可以使用粘合剂等将预发泡面板层压到织物,陶瓷和/或金属片材上。 通过适当选择层压材料的各种元素,即发泡聚合物基体,聚合物织物和陶瓷和金属片材,可以定制各种弹道,阻燃,刚度和其他性能 进入产品用于特定的最终用途应用。
