Abstract
A lightweight ballistic resistant rigid structural panel especially for use in aircraft interiors is disclosed. The rigid structural panel is made up of a core layer including a plurality of sheets of flexible, high-tensile strength fabric interleaved with a plurality of sheets of a thermal-fusible film adhesive, and a sheet of cushioning material adhered to the plurality of sheets of flexible, high-tensile strength fabric. Fiber-reinforced face skins are adhered to exterior surfaces of the panel core for structural strength and rigidity. The rigid structural panel is capable of resisting ballistic attack from handguns and like weapons, while maintaining a high degree of strength and rigidity.
Claims19
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.
