Patent ID: 8904737

Claim:
A fiber-reinforced polymeric load-bearing building panel having a length, a top and a bottom, and comprising: (a) an outer fiber-reinforced polymeric layer about 0.10 inch thick to about 0.15 inch thick, said outer layer comprising a first set of continuous fibers in a first reaction-cured resin, said outer layer defining a first outermost surface of said building panel; (b) an inner fiber-reinforced polymeric layer about 0.10 inch thick to about 0.15 inch thick, said inner layer comprising a second set of continuous fibers in a second reaction-cured resin, said inner layer defining a second outermost surface of said building panel; and (c) a plurality of load-bearing studs, spaced along the length of said building panel and extending, from said inner layer, away from the second outermost surface to end panels ( 130 ) of said studs, including away from said building panel, said studs extending along the height of said building panel, and having walls, defining outer surfaces of said studs, about 0.10 inch thick to about 0.15 inch thick, said walls of said studs comprising a third set of continuous fibers in a third reaction-cured resin, said building panel having a thickness between said inner layer and said outer layer, excluding any dimensions of said studs, of about 2 inches to about 5 inches, said building panel having a mass of no more than 8.9 pounds per foot of height per linear foot length of said building panel, and a vertical crush resistance of at least 4000 pounds per linear foot length of said building panel when a load is evenly distributed over the length and the thickness of said building panel.
