COMPOSITE WOOD PRODUCT AND METHOD OF MANUFACTURE UTILIZING WOOD INFECTED BY BARK BEETLES

摘要

This application reveals a methodology for making a preserved composite wood product from wood infested with a fungus associated with a bark beetle, and the preserved composite wood product produced thereby. In one embodiment, the method involves profiling lumber to remove a portion of fungus infested wood or bark, leaving a profiled board having a bonding surface comprising a remaining portion of fungus infested wood, treating the profiled board with a liquid comprising a lumber additive, so that the board absorbs the liquid and the remaining portion of the fungus infested wood on the bonding surface acquires a retained concentration of the lumber additive, to form a treated board, and joining the bonding surface to one or more pieces of wood along a longitudinal junction, to form a composite wood product that has an interior and an exterior, so that an interior segment of the longitudinal junction is formed by the remaining portion of the fungus infested wood on the bonding surface located in the interior of the composite wood product, wherein the retained concentration of the lumber additive in the interior segment is at least as high as the concentration of the lumber additive at any point on the exterior of the composite wood product.
