5. The pallet according to claim 1 further comprising a plurality of fasteners coupling said cargo and base layers to said plurality of support block assemblies, with said plurality of fasteners extending into respective second openings of said second support blocks.
6. The pallet according to claim 1 wherein said first support block is rectangular shaped and the first opening extending therethrough is also rectangular shaped, and wherein said second support block is rectangular shaped and the second opening extending therethrough is also rectangular shaped.
7. The pallet according to claim 1 wherein said first and second support blocks comprise a composite material.
8. The pallet according to claim 7 wherein the composite material comprises wood and plastic.
9. The pallet according to claim 8 wherein the composite material comprises about 50% wood and about 50% plastic.
10. The pallet according to claim 8 wherein the wood comprises at least one of wood dust and wood waste, and wherein the plastic comprises recycled plastic.
11. The pallet according to claim 1 wherein said cargo and base layers each comprises a plurality of wood boards.
12. A pallet comprising:
a cargo layer;
a base layer; and
a plurality of composite support block assemblies separating said cargo and base layers, each composite support block assembly comprising
a first composite support block with a first opening extending therethrough in a horizontal direction,
a second composite support block with a second opening extending therethrough in the horizontal direction,
said first and second composite support blocks comprising a composite material comprising wood and plastic, and
said second composite support block inserted into the first opening of said first composite support block, with interior dimensions of the first opening in said first support block corresponding to exterior dimensions of a single second support block, and with the second opening being orthogonal to the first opening in said first composite support block so as to enclose the second opening.
13. The pallet according to claim 12 wherein exposed outer sidewalls of said second composite support block are aligned with exposed outer sidewalls of said first composite support block.
14. The pallet according to claim 13 wherein interfaces between the exposed outer sidewalls of said first and second composite support blocks are sealed.
15. The pallet according to claim 12 further comprising a plurality of fasteners coupling said cargo and base layers to said plurality of composite support block assemblies, with said plurality of fastener extending into respective second openings of said second composite support blocks.
16. The pallet according to claim 12 wherein the composite material comprises about 50% wood and about 50% plastic.
17. The pallet according to claim 12 wherein the wood comprises at least one of wood dust and wood waste, and wherein the plastic comprises recycled plastic.
18. A method for making a pallet comprising:
providing a cargo layer and a base layer;
forming a plurality of support block assemblies separating the cargo and base layers, forming each support block assembly comprising
forming a first support block with a first opening extending therethrough in a horizontal direction, and
forming a second support block with a second opening extending therethrough in the horizontal direction, and
