the flooring of truck trailers which experience adverse operating conditions such as from heavy loads of lift trucks on the top side and water spray during rainy periods on the bottom side the composite wood board comprises an edge glued laminated wood member composed of wood segments with end joints the wood member is underlaid with a thin layer of fiber reinforced plastic the top surface of the composite wood board is the same as that of the laminated wood the fiber reinforced plastic underlay is composed of glass and or carbon fibers embedded in a polymeric resin such as epoxy phenolic vinyl ester polyester polypropylene or polyamide resin further the fiber reinforced plastic underlay is substantially bonded to the wood member with a reactive hotmelt adhesive the fiber reinforced plastic provides high fatigue resistance to the composite wood board and prevents water leakage into the trailer through the end joints of the wood segments application_number US 73226500 A description the reinforced composite wood flooring of the present invention is an improvement over conventional wood flooring of truck trailers in that it provides both moisture proofing and reinforcement to such flooring in order to understand the benefits provided by the composite wood flooring it is first necessary to understand the construction of conventional laminated wood flooring conventional wood flooring 11 for over the road truck trailers 12 such as that.
