Structural panel and method for producing same

Claim 1

THE METHOD OF MAKING A LIGHTWEIGHT STRUCTURAL PANEL FORM BOARD MATERIAL HAVING FIBERS BONDED TOGETHER AT SPACED APART POINTS AND WHEREIN THE FIBERS ARE GENERALLY PARALLEL TO OPPOSITE SURFACES OF THE MATERIAL, SAID METHOD COMPRISING THE STEPS OF COATING ONE OF SAID OPPOSITE SURFACES OF EACH OF A PLURALITY OF SECTIONS OF THE BOARD MATERIAL WITH A HARDENABLE BONDING MATERIAL, ASSEMBLING THE COATED SECTIONS IN JUXTAPOSITION WITH A COATED SURFACE OF EACH SECTION ADJACENT ONE OF SAID SURFACES OF AN ADJACENT SECTION, APPLYING A PRESSURE TO AN ENDMOST COATED SECTION TO FORCE THE SECTIONS TOGETHER AND CAUSE THE BONDING MATEIRAL TO FLOW GENERALLY LATERALLY INTO JUXTAPOSED SECTIONS FROM THEIR ADJACENT SURFACES, CUTTING THE ASSEMBLED SECTIONS OF MATERIAL AT RIGHT ANGLES TO THE COATED SURFACES TO FORM A PLURALITY OF STRIPS HAVING OPPOSITELY DISPOSED SURFACES NORMAL TO THE PREVIOUSLY COATED SURFACES, APPLYING A LAYER OF A HARDENABLE BONDING MATERIAL TO EACH OF SAID OPPOSITELY DISPOSED SURFACES, EMBEDDING A REINFORCING MATERIAL IN EACH OF SAID LAYERS OF BONDING MATERIAL, FORCING A PORTION OF THE BONDING MATERIAL INTO SAID OPPOSITELY DISPOSED SURFACES, CAUSING THE LAYERS OF REINFORCED BONDING MATERIAL TO HARDEN AND FORM REINFORCING SKINS ON OPPOSITELY DIPOSED SURFACES, AND CAUSING THE BONDING MATERIAL IN ADJACENT REGIONS OF SAID STRIPS TO HARDEN AFTER BEING FORCED LATERALLY PAST FIBERS IN ADJACENT REGIONS OF SAID STRIPS TO FORM AREAS OF REINFORCEMENT EXTENDING BETWEEN SAID SKINS.
