Ultra high molecular weight polyethylene ballistic structures
View Patent ↗Ballistic panels formed by the lamination of highly oriented ultra high molecular weight poly(ethylene) slit films and sheets useful in the fabrication of ballistic containers are described.
1. A ballistic panel comprising a laminated structure of a plurality of highly oriented ultra high molecular weight polyethylene slit film, sheets or tapes having a generally rectangular cross-section and smooth cut edges and a heat of fusion above about 243 joules/gram.
2. The ballistic panel of claim 1 wherein said ultra high molecular weight polyethylene slit film fibers, tapes, sheets or films have a thickness below about 3 mils.
3. The ballistic panel of claim 2 having a thickness above about ¼ inch.
4. The ballistic panel of claim 3 having a thickness above about ½ inch.
5. The ballistic panel of claim 3 comprising a plurality of individual layers of highly oriented ultra high molecular weight polyethylene slit film sheets or tapes having a generally rectangular cross-section and smooth cut edges and a heat of fusion above about 243 joules/gram laminated directly to each other without an adhesive mechanism.
6. The ballistic panel of claim 3 comprising individual layers of highly oriented ultra high molecular weight polyethylene slit film sheets or tapes having a generally rectangular cross-section and smooth cut edges and a heat of fusion above about 243 joules/gram laminated directly to each other with an adhesive mechanism.
