摘要: A ballistic protection composite shield is disclosed, with improved next-to-skin properties, and improved flexibility. Needlepunching technology permits the manufacture of the wear layer using any type of fiber, and advantageously allows distinct layering, fiber blending, compressibility, controlled fiber orientation, and increases z-directional strength. Needlepunching the nonwoven wear layer to the woven antiballistic layer mechanically interconnects the two layers, eliminating the need for an adhesive bond and increasing the flexibility of the shield. An abrasion resistant strike layer, such as leather, increases the life of the shield.
