<p>A ballistic composite comprises multiple layers of a fabric having unidirectional ballistic resistant yarns in at least two layers and a resin layer between each pair of such multiple layers adhered to the ballistic resistant yarns but not encapsulation the same and not penetrating the layer of fabric. The ballistic yarn layers are at 90°±5° with respect to each other and the ballistic resistant yarns are stabilized by being woven in a second fabric. The second fabric is formed of yarns having a substantially lower tenacity and tensile modulus than the ballistic resistant yarn. The ballistic resistant yarns have a tenacity of at least about 15 grams per denier and a modulus of at least about 40 grams per denier. The resin in the resin layer has a modulus of at least about 7000 psi.</p> |
