A method and structure is disclosed for oriented strand boards that utilize a 3-layer, sandwich-type structural panel. The two outer faces are preferably made of wood flakes and the inner core preferably is made out of compression resistant products such as wood chips, paper mill sludge or recycled paper. The core is either a continuous perforated mat or a plurality of individual chunks of compression resistant materials, and preferably contains voids to provide for a reduction in weight of the board.

The panel according to claim 2, wherein said perforated mat consists essentially of vulcanized rubber.12. The panel according to claim 2, wherein said perforated mat consists essentially of thermoset plastics.13. The panel according to claim 1, wherein said core comprises a plurality of individual chunks of compression-resistant material that are so oriented that voids between adjacent chunks have boundaries that are in a direction essentially orthogonal to said plane defined by said first oriented strand face.14. The panel according to claim 13, wherein said core further comprises inorganic filler in the amount of 10% to 80% by weight.15. The panel according to claim 14, wherein said inorganic filler comprises one or more of clay, calcium carbonate, and titanium dioxide.16. The panel according to claim 13, wherein said core comprises between 0% and 75% voids by volume and wherein said core further comprises resin hinder in an amount of less than 10% by weight.17. The panel according to claim 16, wherein said compression resistant material comprises one or more of paper mill sludge, wood chips, recycled paper, vulcanized rubber, thermoset plastics, and volcanic rock.18. The panel according to claim 13, wherein said core comprises between 0% and 50% voids by volume and wherein said core further comprises resin binder in an amount of less than 5% by weight.19. The panel according to claim 13, wherein said compression-resistant material consists essentially of paper mill sludge.20. The panel according to claim 13, wherein said compression-resistant material consists essentially of wood chips.21. The panel according to claim 13, wherein said compression-resistant material consists essentially of recycled paper.22. The panel according to claim 13, wherein said compression-resistant material consists essentially of vulcanized rubber.23. The panel according to claim 13, wherein said compression-resistant material consists essentially of thermoset plastics.24.
