Disclosed is to a composite material, a structural element comprised of the composite material, an airplane wing spar and their methods of production. Some embodiments of the present invention include composite materials comprised of multiple layers of arrays of metallic bodies separated by layers of non-metallic material, wherein the orientation of metallic bodies in some metallic layers is structurally complementing to the orientation of metallic layers in adjacent metallic layers. Other embodiments of the present invention include structural elements, such as an airplane wing spar, comprised of the composite material.

1. A composite material comprising: at least two metallic arrays of rigid oblong metallic bodies, wherein said metallic bodies have a tensile strength of 1140 MPa or greater, are at least 0.3 millimeters (mm.) thick, at least 2 mm wide and at least 10 mm long and spaces between the metallic bodies w
1. A composite material comprising: at least two metallic arrays of rigid oblong metallic bodies, wherein said metallic bodies have a tensile strength of 1140 MPa or greater, are at least 0.3 millimeters (mm.) thick, at least 2 mm wide and at least 10 mm long and spaces between the metallic bodies within each of the at least two metallic arrays are filled with a non-metallic filler;a separating non-metallic layer between each given two metallic arrays of the at least two metallic arrays, each of said separating non-metallic layers being comprised of polymer fabric or carbon fiber residing contiguously between the given two metallic arrays; andtwo exterior non-metallic layers comprised of polymer fabric or carbon fiber contiguously residing on an exterior side of an exterior metallic array of said at least two metallic arrays;wherein said at least two metallic arrays and said separating and exterior non-metallic layers are arranged in contiguous alternating layers, starting and ending with a non-metallic layer, to form a solid composite material having a non-metallic exterior surface. 2. The material according to claim 1, wherein the orientation of said metallic bodies in a first metallic array of the at least two metallic arrays is structurally complementing to the orientation of said metallic bodies in a second metallic array of the at least two metallic arrays, which second metallic array is adjacent to said first metallic array. 3. The material according to claim 2, wherein the orientation of said metallic bodies in said first metallic array is substantially perpendicular to the orientation of one or more of said metallic bodies in said second metallic array. 4. The material according to claim 1, wherein said metallic bodies have a substantially rectangular cross section, such that said metallic bodies have at least one flat surface facing an exterior surface. 5. The material according to claim 1, wherein said layers and arrays are attached to each other by an adhesive substance. 6. The material according to claim 1, wherein said metallic arrays are continuous metallic arrays. 7. The material according to claim 5, wherein at least a portion of said metallic bodies are individually wrapped by a strip of polymer fabric or carbon fiber, prior to adhesion to said non-metallic layers. 8. The material according to claim 1, wherein said metallic bodies are connected by perpendicular auxiliary metal connectors to form a continuous integral metal grid form, wherein each of said connectors protrudes from both sides of metallic bodies it connects. 9. A structural element comprised of: a component for providing structural integrity comprised of: first and second metallic arrays composed of an array of rigid oblong metallic bodies having a tensile strength of 1140 MPa or greater, wherein the orientation of one or more of said metallic bodies in said second metallic array is structurally complementing to the orientation of one or more of said metallic bodies in said first metallic array and spaces between the metallic bodies within each of said first and second metallic arrays are filled with a non-metallic filler;two exterior non-metallic layers comprised of polymer fabric or carbon fiber contiguously residing on an exterior side of said component; anda separating non-metallic layer comprised of polymer fabric or carbon fiber situated contiguously between said first and second metallic arrays;wherein said first and second metallic arrays and said exterior and separating non-metallic layers are arranged in contiguous alternating layers, starting and ending with a non-metallic layer, to form a solid composite material having a non-metallic exterior surface. 10. The structural element according to claim 9, wherein the orientation of one or more of said metallic bodies in said second metallic array is substantially perpendicular to the orientation of one or more of said metallic bodies in said first metallic array. 11. The structural element according to claim 9, wherein said metallic bodies have a substantially rectangular cross section, such that said metallic bodies have at least one flat surface facing an exterior surface. 12. The structural element according to claim 9, wherein said layers and arrays are attached to each other by an adhesive substance. 13. The structural element according to claim 9, wherein said metallic arrays are continuous metallic arrays. 14. The structural element according to claim 12, wherein at least a portion of said metallic bodies are individually wrapped by a strip of polymer fabric or carbon fiber, prior to adhesion to said non-metallic layers. 15. The structural element according to claim 9, wherein one or more of said metallic bodies are arranged and connected such that they form a pre-planned electric circuit. 16. An airplane wing spar comprised of: a spar for providing structural integrity to an airplane wing comprising: first and second metallic arrays composed of an array of rigid oblong metallic bodies having a tensile strength of 1140 MPa or greater, wherein the orientation of one or more of said metallic bodies in said second metallic array is structurally complementing to the orientation of one or more of said metallic bodies in said first metallic array and spaces between the metallic bodies within each array are filled with a non-metallic filler;two exterior non-metallic layers comprised of polymer fabric or carbon fiber contiguously residing on an exterior side of said spar; anda separating non-metallic layer comprised of polymer fabric or carbon fiber situated contiguously between said first and second metallic arrays;wherein said metallic arrays and said exterior and separating non-metallic layers are arranged in contiguous alternating layers, starting and ending with a non-metallic layer, to form a solid composite material having a non-metallic exterior surface. 17. The airplane wing spar according to claim 16, wherein the orientation of one or more of said metallic bodies in said second metallic array is substantially perpendicular to the orientation of one or more of said metallic bodies in said first metallic array. 18. The airplane wing spar according to claim 16, wherein said metallic bodies have a substantially rectangular cross section, such that said metallic bodies have at least one flat surface facing an exterior surface. 19. The airplane wing spar according to claim 16, wherein said layers and arrays are attached to each other by an adhesive substance. 20. The airplane wing spar according to claim 16, wherein said metallic arrays are continuous metallic arrays. 21. The airplane wing spar according to claim 19, wherein at least a portion of said metallic bodies are individually wrapped by a strip of polymer fabric or carbon fiber, prior to adhesion to said non-metallic layers. 22.
