Material for and the method of manufacture for ballistic shielding
A ballistic resistant curtain system is provided formed of a plurality of aligned ballistic material panels. Panels protect vertical surfaces, and can be reconfigured for horizontal surfaces or other oriented areas. Adjacent panels may be are aligned end to end in a butt or overlap manner, or configured to be angularly disposed toward the direction of fire such as to form a line of sight overlap. Each panel is formed of high strength fibers made from materials such as extended chain ultra-high molecular weight polyethylene. An exterior coating formed of fabric, polyurethane, or other material provides both an acoustic attenuation or sound absorbing surface as well as an aesthetic facing for providing an improved visual appearance to the area. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
