HIGH PERFORMANCE BALLISTIC COMPOSITES HAVING IMPROVED FLEXIBILITY AND METHOD OF MAKING THE SAME |
摘要 |
<p>A composite material which has excellent ballistic performance and has im proved flexibility. Surprisingly, it has been found that a combination of po ly(alpha-olefin) fiber and matrix resin provides these desirable product fea tures. The resin matrix is a block copolymer of a conjugated diene and a vin yl aromatic monomer, preferably a styrene-isoprene-styrene block copolymer, that is applied as an aqueous composition. The fiber has a tenacity of at le ast about 35 g/d and a tensile modulus of at least about 1200 g/d. The compo site has a total density equal to or less than about 100 g/m2 and a stiffnes s of less than about 2.5 pounds (1.14 kg) for a two layer structure of the c omposite, and a total areal density equal to or less than about 190 g/m2 and a stiffness of less than about 3.0 pounds (1.36 kg) for a four layer struct ure of the composite. The Peel Strength for a two layer structure of less th an about 1.0 pounds (0.45 kg) for a two layer structure of the composite, an d less than about 0.7 pounds (0.32 kg) for a four layer structure of the com posite. The process of this invention permits fabrication of these desirable products in a cost-effective manner. Body armor made from the composite has improved flexibility and excellent ballistic characteristics.</p> |
