Abstract
A method and apparatus comprising combining fragment resistant fabrics in multiple layers in a resin, wherein the multiple layers present a fragment projectile with alternating tougher and softer resistances to penetration to enhance the stopping power of the composite armor while retaining a lightweight configuration is disclosed.
Claims20
A composite armor comprising:
- a first layer having a plurality of plies of a first material encased front and back by a plurality of plies of a second material
- a second layer having a plurality of plies of the first material encased front and back by a plurality of plies of a third material,
- the armor impregnated with a resin, wherein the armor weighs less than 4.5 pounds per square foot of protected area, can operate continuously at 500° F., and can stop an object weighing 1.1 pounds travelling at least 760 feet per second generating at least 15,000 foot pounds of force.
A composite armor comprising:
- a first layer of fabric,
- a second layer of fabric coupled to the first layer being different than the first layer,
- a third layer of fabric coupled to the second layer being different than the second layer,
- a fourth layer of fabric coupled to the third layer being different than the third layer,
- a fifth layer of fabric coupled to the fourth layer being different than the fourth layer,
- a sixth layer of fabric coupled to the fifth layer being different than the fifth layer,
- wherein the adjacent layers of differing fabric have greater stopping power for being adjacent as described than a similar number of plies of either material, the armor weights less than 4.5 pounds per square foot, can operate continuously at 500° F., and can stop an object weighing 1.1 pounds travelling at least 760 feet per second generating at least 15,000 foot pounds of force.
