Abstract:
A lightweight ballistic resistant rigid structural panel, comprising:a plurality of sheets of flexible, high-tensile strength fabric interleaved with a plurality of sheets of a fusible film adhesive; a sheet of cushioning material adhered to the plurality of sheets of flexible, high-tensile strength fabric to form a panel core not less than about 0.25 inches thick; a first fiber-reinforced face skin adhered to a surface of the panel core; and a second fiber-reinforced face skin adhered to the panel core opposite to the first fiber-reinforced face skin, wherein the panel core is interposed between the first fiber-reinforced face skin and the second fiber-reinforced face skin so as to stiffen the rigid structural panel by being bonded to the first and second fiber-reinforced face skins while maintaining a uniform separation therebetween, and the first and second fiber-reinforced face skins are each configured to have a tensile strength not less than about 40,000 PSI and a thickness not less than about 0.06 inches.
