Abstract:
1. 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 ( 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.
