A ballistic and/or fire barrier for protecting objects in an interior of a vehicle due to projectile penetration and/or fire includes one or more layers of high strength fabric positioned towards an outer shell of the vehicle. The high strength fabric is substantially fixedly or fixedly positioned with respect to the outer shell of the vehicle. In another embodiment, the ballistic and/or fire barrier protects objects in a structure from damage due to projectile penetration. The ballistic and/or fire barrier includes at least one layer of high strength fabric positioned towards an outer housing of the structure. The high strength fabric is substantially fixedly positioned with respect to the structure towards either the inner or outer surface of the outer housing. In another embodiment of the present invention, a ballistic barrier protects a wearer of the ballistic barrier from damage due to projectile penetration. The ballistic barrier comprises first and second portions positioned generally parallel each other. The first portion includes one or more layers of high strength fabric while the second portion is generally impact-resistant. Preferably, the layer of high strength fabric comprise a plurality of plies. One of the plies can comprise woven fibers. Another of the plies can be a felt. Also preferably, the layer of high strength fabric in the ballistic barrier embodiments comprises a polymer material such as one or more of aramid material, polyethylene material, and polybenzoxazole material.

1. A ballistic barrier preventing penetration by a foreign body in combination with an outer shell of an aircraft, the outer shell defining the interior of the aircraft, the ballistic barrier in combination with the outer shell comprising:at least one layer of fabric disposed in the interior of the aircraft, wherein the at least one layer of fabric is capable of absorbing kinetic energy of the foreign body, the at least one layer of fabric being substantially positioned towards the interior of the aircraft with respect to the outer shell and at a finite distance away from the outer shell, and wherein the at least one layer of fabric is composed of one or more ballistic material selected from a group consisting of aramid, polyethylene and phenylenebenzole, and wherein the at least one layer of fabric includes at least two plies and wherein one of the plies is felt. 2. The ballistic barrier as recited in claim 1, wherein the felt being positioned outward of the remaining plies with respect to the interior.3. The ballistic barrier as recited in claim 1, wherein at least one of the plurality of plies includes woven fibers.4. The ballistic barrier as recited in claim 1, wherein the at least one layer of fabric is fire resistant.5. The ballistic barrier as recited in claim 1, wherein the foreign body includes projectile or fragment munitions.6. The ballistic barrier as recited in claim 1, wherein the aircraft includes an inner panel, and wherein the at least one layer of fabric is positioned between the outer shell and the inner panel of the aircraft.7. A ballistic barrier in combination with an outer housing of a structure, the outer housing defining an interior, for protecting objects in the interior of the structure from damage, the ballistic barrier in combination with said outer housing comprising:two or more layers of fabric disposed in the interior of the structure, the two or more layers of fabric being substantially positioned towards the outer housing of the structure and at a finite distance away from said outer housing of the structure, wherein at least one layer of fabric is capable of absorbing kinetic energy of a foreign body; and wherein a first of the two or more layers of fabric is a felt, the felt being positioned toward the outer housing of the structure with respect to the other layers of fabric. 8. The ballistic barrier as recited in claim 7, wherein at least one of the two or more layers of fabric is composed of one or more ballistic material selected from a group consisting of aramid, polyethylene and phenylenebenzole.9. The ballistic barrier as recited in claim 7, wherein one of the two or more layers of fabric is fire resistant.10. The ballistic barrier as recited in claim 7, wherein the structure includes a vehicle.11. The ballistic barrier as recited in claim 7, wherein the structure includes an aircraft.12. A method for protecting objects in an interior of a structure from damage, the structure having an outer shell defining the interior of the structure, the method comprising:positioning at least one layer of fabric in the interior of the structure towards the outer shell of the structure and at a finite distance away from the outer shell, wherein the at least one layer of fabric is capable of absorbing a kinetic energy of a fragment or a projectile; and attaching the at least one layer of fabric to the structure such that the at least one layer of fabric is substantially positioned towards the interior of the structure with respect to the outer shell and at a finite distance away from the outer shell such that upon impact from the fragment or the projectile the fabric tends to detach from the structure, the at least one layer of fabric composed of one or more ballistic material selected from a group consisting of aramid, polyethylene and phenylenebenzole; wherein the at least one layer of fabric includes a plurality of plies; wherein one of the plurality of plies is a felt, the felt being positioned outward of the remaining plies with respect to the interior. 13. A ballistic fire barrier in combination with a vehicle, the vehicle having an outer shell defining an interior, the ballistic fire barrier in combination with the vehicle comprising:two or more layers of fire resistant fabric disposed in the interior of the vehicle and substantially fixedly positioned towards the interior of the vehicle with respect to the outer shell of the vehicle and at a finite distance away from the outer shell, wherein a first of the two or more layers of fire resistant fabric is capable of absorbing kinetic energy of a fragment or a projectile and a second of the two or more layers of fire resistant fabric is a felt, the second layer being positioned outward of the first layer with respect to the interior of the vehicle. 14. The ballistic fire barrier as recited in claim 13, wherein at least one of the two or more layers of fire resistant fabric includes a plurality of plies.15. The ballistic fire barrier as recited in claim 13, wherein at least one of the two or more layers of fire resistant fabric is composed of one or more ballistic material selected from a group consisting of aramid, polyethylene and phenylenebenzole.16. The fire barrier as recited in claim 13, wherein the fire resistant fabric is detachably fixed to a frame disposed between the outer shell and an inner panel such that upon impact from the fragment or the projectile the fire resistant fabric tends to detach from the frame.17.
