Biomimetic tendon-reinforced" (BTR) composite structures feature improved properties including a very high strength-to-weight ratio. The basic structure includes plurality of parallel, spaced-apart stuffer members, each with an upper end and a lower end, and a plurality of fiber elements, each having one point connected to the upper end of a stuffer member and another point connected to the lower end of a stuffer member such that the elements form criss-crossing joints between the stuffer members. The stuffer members and fiber elements may optionally be embedded in a matrix material such as an epoxy resin. The fiber elements are preferably carbon fibers, though other materials, including natural or synthetic fibers or metal wires may be used. The stuffer members may be rods, tubes, or spheres, and may be constructed of metal, ceramic or plastic. The stuffer members are preferably spaced apart at equal distances. If the members are tubes, the fiber elements may be dressed through the tubes. Alternatively, the fiber elements may tied to the ends of the stuffer members and/or to each other at the joints. Both linear and planar structures are disclosed.

I claim: 1. A biomimetic tendon-reinforced (BTR) composite structure, comprising: a plurality of parallel, spaced-apart rigid stuffer members of substantially equal height, each stuffer member having an upper end and a lower end, and wherein the upper ends and the lower ends of the stuffer members
I claim: 1. A biomimetic tendon-reinforced (BTR) composite structure, comprising: a plurality of parallel, spaced-apart rigid stuffer members of substantially equal height, each stuffer member having an upper end and a lower end, and wherein the upper ends and the lower ends of the stuffer members are arranged along upper and lower parallel lines, respectively; and a plurality of fiber elements, including one fiber element that connects to the upper and lower ends of adjacent stuffer members in alternating fashion, and another fiber element that connects to the opposite ends of the same stuffer members in alternating fashion, such that the fiber elements criss-cross each other between the stuffer members. 2. The structure of claim 1, wherein the stuffer members and fiber elements are embedded in a matrix material. 3. The structure of claim 1, wherein the stuffer members and fiber elements are embedded in an epoxy resin. 4. The structure of claim 1, wherein the stuffer members are rods, tubes, ellipsoids or spheres. 5. The structure of claim 1, wherein the stuffer members are metal, ceramic or plastic. 6. The structure of claim 1, wherein the stuffer members are spaced apart at equal distances or at variable distances determined through optimization. 7. The structure of claim 1, wherein the fiber elements are carbon fibers, nylon, aramid fibers, glass fibers, plant fibers; or metal wires. 8. The structure of claim 1, wherein: the stuffer members are tubes; and the fiber elements run through the tubes. 9. The structure of claim 1, wherein the fiber elements are tied to the ends of the stuffer members. 10.

The structure of claim 1, further including a panel bonded to the upper or lower ends of the stuffer members. 12. The structure of claim 1, wherein: the stuffer members are arranged in two-dimensional rows such that the upper and lower ends of the members respectively define upper and lower surfaces; and further including material bonded to one or both of the surfaces. 13. The structure of claim 1, wherein: the stuffer members are arranged in two-dimensional rows such that the upper and lower ends of the members respectively define upper and lower surfaces; and further including a solid panel bonded to one or both of the surfaces. 14. The structure of claim 1, wherein: the stuffer members are arranged in two-dimensional rows such that the upper and lower ends of the members respectively define upper and lower surfaces; and further including a mesh panel bonded to one or both of the surfaces. 15. The structure of claim 1, wherein: the stuffer members are arranged in two-dimensional rows such that the upper and lower ends of the members respectively define upper and lower surfaces; and further including additional fiber elements connecting the ends of the members. 16. The structure of claim 12, wherein the stuffer members and fiber elements are embedded in a matrix material. 17. The structure of claim 12, wherein the stuffer members and fiber elements are embedded in an epoxy resin. 18. The structure of claim 12, wherein the stuffer members are rods, tubes, or spheres. 19. The structure of claim 12, wherein the stuffer members are metal, ceramic or plastic. 20. The structure of claim 12, wherein the stuffer members are spaced apart at equal distances. 21. The structure of claim 12, wherein the fiber elements are carbon fibers. 22. The structure of claim 12, wherein: the stuffer members are tubes; and the fiber elements run through the tubes. 23. The structure of claim 12, wherein the fiber elements are tied to the ends of the stuffer members. 24. The structure of claim 12, wherein the fiber elements are tied to one another where they criss-cross, forming joints.
