Composite wood flooring

A composite vehicular trailer flooring system having an exposed wood upper surface, the vehicular trailer floor having a longitudinal length and a lateral width, said composite vehicular trailer flooring system comprising:

• a plurality of wood boards extending longitudinally up to a length substantially equal to the longitudinal length of said vehicular trailer floor, each wood board of said plurality of wood boards having a top surface, a bottom surface opposite said top surface, and a first side surface and second side surface extending between said top surface and said bottom surface, and a board width that is less than the lateral width of said vehicular trailer floor, each wood board being formed of a plurality of wood segments joined to one another by coupling portions;
• said plurality of wood boards being arranged such that at least one of said first side surface and said second side surface of each of said wood boards approximates one of said first side surface and said second side surface of adjacent boards or a mating portion of a metallic component of the trailer to form a continuous trailer floor having an upper wood surface and a bottom surface for extending for the lateral width of the vehicular trailer floor, a joint region being formed at locations at which said first side surface or said second side surface of adjacent boards approximate one another;
• each of the plurality of wood boards of said composite wood flooring system further comprising a substantially planar polymer layer formed of a fiber reinforced polymer, said polymer layer being substantially continuously bonded to said bottom surface of each of the plurality of wood boards of said trailer floor and extending unitarily substantially across the width and along the longitudinal length of each wood board, the upper wood surface of each of the plurality of wood boards being essentially uncoated by fiber reinforced polymer, and wherein about 70% to about 100% of the fibers of said fiber reinforced polymer extend in a direction substantially parallel to the longitudinal length of the boards of the trailer floor, and the fibers are glass fibers, carbon fibers, or mixtures thereof;
• and
• whereby said substantially continuous planar polymer layer of fiber reinforced polymer bonded to the bottom surface of each of the plurality of wood boards of the trailer floor resists pop-out of the wood segments at the coupling portions and improves one or more of the flexural modulus, strength and load carrying capacity of the vehicular trailer floor.
