ABSTRACT:
This invention provides a multi-layer material designed to cover ceramic armor applied to military vehicles, which suppresses ceramic shrapnel created during a ballistic event up to the magnitude of a 0.50 caliber at 2000-2200 feet per second at zero degree obliquity. This material is a laminate comprising of three distinct layers of fabric. The middle layer is a heavy ballistic nylon or polyester fabric. A nylon fabric of this nature weighs between fifteen to thirty-five ounces per square yard and a polyester fabric of this nature weighs between fifteen to thirty-five ounces per square yard. This fabric can be either woven or knitted. The outer layer that is attached to the middle layer can be any type of decorative fabric, including woven, nonwoven and knit fabrics. This fabric should be relatively light weight and dyeable. The bottom layer of fabric is a loop pile, warp knit, weft-inserted fabric. The length of each loop, yarn type, and denier is adapted to comport to a particular hook system utilized on a particular military vehicle. These three layers of fabric are adhesively attached to each other.
