ABSTRACT:
A puncture proof material is provided. The material includes a first mat that is woven using metal strips forming a warp and a weft of the first mat. The metal strips have a capture device near the center of each intersection of the warp and weft of the first mat. The capture device can be implemented with a hole, depression or etched rectangular hole near the center of each intersection of the warp and weft of the first mat. A second mat, woven of metal strips having a capture device near the center of each intersection of the warp and weft of the second mat, overlays the first woven mat. Additional mats can be overlaid to increase the puncture proof characteristic of the material. Another capture device implementation includes a top layer woven of annealed metal foil of relatively low tensile strength overlaid over other randomly overlaid layers each woven of metal foil of higher tensile strength.
