A protective device for use in containing high energy debris and pressure is provided which employs a plurality of energy absorption elements disposed on an outer surface of a rigid inner sheet, where the outer surface faces away from the body being protected and toward the high energy event, such as an explosion. Each energy absorption element extends generally away from the body to permit the high energy event to first impact upon the energy absorption elements, rather than the body. Energy absorption elements are formed of laminate composite materials. As such, energy absorption elements are configured to contain or reduce high energy debris material and pressure impacting the energy absorption element through delamination and possibly penetration of the composite material.

That which is claimed: 1. A composite armor panel configured to absorb energy to protect a body from the impact of a high energy event, the panel comprising: a rigid inner sheet defining opposite inner and outer surfaces, the inner surface directed toward the body; a plurality of energy absorption elements disposed on the outer surface of the inner sheet, each energy absorption element formed of a laminate composite material configured with a terminating end attached to the inner sheet and at least a first portion, not attached to the inner sheet, extending from the terminating end generally outward from the inner sheet such that each energy absorption element is configured to be deformed inwardly by the impact and thereby at least partially delaminate the laminate composite material of the energy absorbing element, wherein each energy absorption element is distinct from each other energy absorption element, and wherein a tangent to the first portion of each energy absorption element intersects the inner sheet; and an outer sheet defining opposite interior and exterior surfaces, the interior surface directed toward the body, the inner sheet, and the plurality of energy absorption elements. 2. A composite armor panel according to claim 1 wherein each of the energy absorption elements defines a generally S-shaped configuration. 3. A composite armor panel according to claim 1 wherein at least a plurality of the energy absorption elements at least partially overlap an adjacent one of the energy absorption elements. 4. A composite armor panel according to claim 1 wherein the energy absorption elements extend generally in parallel and equidistant outward from the inner sheet and being spaced equidistant along the inner sheet. 5. A composite armor panel according to claim 1 wherein the laminate composite material of the energy absorption elements includes a reinforcement material disposed in a matrix material. 6. A composite armor panel according to claim 1 wherein the energy absorption elements and inner sheet comprise a unitary composite member. 7. A composite armor panel according to claim 1 wherein the inner sheet defines a plurality of perforations. 8. A composite armor panel according to claim 1 wherein at least one energy absorption element is further configured for fiber breakage by the impact. 9. A composite armor panel according to claim 1 wherein the panel is personnel body armor, the inner sheet being configured to correspond to the shape of a portion of a human body. 10. A composite armor panel according to claim 1 wherein the panel is vehicle body armor, the inner sheet being configured to correspond to the shape of a portion of a vehicle. 11. A body armor system for protecting a body from the impact of a high energy event, the system comprising: at least one panel comprising a rigid inner sheet defining opposite inner and outer surfaces; a plurality of energy absorption elements disposed on the outer surface of the inner sheet, each energy absorption element formed of a laminate composite material configured with a terminating end attached to the inner sheet and at least a first portion, not attached to the inner sheet, extending from the terminating end generally outward from the inner sheet such that each energy absorption element is configured to be deformed inwardly by the impact and thereby at least partially delaminate the laminate composite material of the energy absorbing element, wherein each energy absorption element is distinct from each other energy absorption element, and wherein a tangent to the first portion of each energy absorption element intersects the inner sheet, wherein the at least one panel is configured to be disposed on the outer surface of the body with the outer surfaces of the inner sheet directed away from the body such that at least one panel is disposed between the body and the impact; and an outer sheet defining opposite interior and exterior surfaces, the interior surface directed toward the body, the inner sheet, and the plurality of energy absorption elements. 12. A body armor system according to claim 11, further comprising a plurality of panels, each panel comprising a rigid inner sheet defining opposite inner and outer surfaces, and wherein the plurality of panels are configured to be disposed on the outer surface of the body with the outer surfaces of the inner sheets directed away from the body. 13. A body armor system according to claim 12 wherein each of the panels is configured to correspond to a respective portion of a vehicle such that the system is configured to be fitted to the vehicle. 14. A body armor system according to claim 12 wherein the panels are configured to define an interior compartment, the energy absorption elements extending generally outward from each inner sheet and toward the interior compartment, such that the panels are configured to protect the vehicle from the impact of a high energy event occurring in the interior compartment. 15. A body armor system according to claim 11 wherein each of the energy absorption elements defines a generally S-shaped configuration. 16. A body armor system according to claim 11 wherein at least a plurality of the energy absorption elements at least partially overlap an adjacent one of the energy absorption elements. 17. A body armor system according to claim 11 wherein the energy absorption elements of the at least one panel extend generally in parallel and equidistant outward from the inner sheet and being spaced equidistant along the inner sheet of the at least one panel. 18. A body armor system according to claim 11 wherein the composite material of the energy absorption elements includes a reinforcement material disposed in a matrix material. 19. A body armor system according to claim 11 wherein the energy absorption elements and inner sheet comprise a unitary composite member. 20. A body armor system according to claim 11 wherein each inner sheet defines a plurality of perforations. 21. A method of protecting a body from the impact of a high energy event, comprising: providing a rigid inner sheet defining opposite inner and outer surfaces, the inner surface directed toward the body; providing a plurality of energy absorption elements disposed on the outer surface of the inner sheet, each energy absorption element formed of a laminate composite material configured with a terminating end attached to the inner sheet and at least a first portion, not attached to the inner sheet, extending from the terminating end generally outward from the inner sheet such that each energy absorption element is configured to be deformed inwardly by the impact and thereby at least partially delaminate the laminate composite material of the energy absorbing element, wherein each energy absorption element is distinct from each other energy absorption element, and wherein a tangent to the first portion of each energy absorption element intersects the inner sheet; and providing an outer sheet defining opposite interior and exterior surfaces, the interior surface directed toward the body, the inner sheet, and the plurality of energy absorption elements. 22. A method according to claim 21, further comprising the step of delaminating the composite material to absorb energy of the impact.
