A shipping pallet typically consists of a solid deck or slats and runners arranged to provide a top surface and legs or posts to provide open access underneath for a forklift type device and is used to store and/or transport a variety of products. The composite ecological shipping pallet of the present invention offers significant advantage over present state of the art in the field. It is stronger, lighter, stiffer and more rigid, more economical, and ecologically sound. The present invention features a combination of design elements that utilize the most effective geometric shapes to increase strength and reduce weight. It allows manufacture from a multitude of potential materials and even allows combinations of different materials within the same component so as to enhance desirable features. With the above stated improvements in the art, the present invention satisfies a need in the marketplace and materially effects world commerce a nd preservation of the ecology.
1) A load bearing structure comprised of arch elements placed adjacent to each other wherein tensile stresses, induced by a bending moment imposed upon on the structure from an applied load, are canceled or partially canceled by virtue of the arch elements' direct or indirect interference with adjacent elements, which place the material of construction into compressive stress and create an offsetting or partially offsetting compressive force within and between the elements.
2) A load bearing structure comprised of a plurality of arch elements rotated through some finite angle arranged so as to directly or indirectly contact adjacent like elements of some finite angle in order to place the material of construction into compressive stress canceling or partially canceling tensile stresses induced by a bending moment imposed upon the structure by an applied load.
