A composite wood panel is manufactured from thin wood laminae cut from wood unsuitable for peeler logs or dimensional lumber. At least one bonding agent is applied to the wood laminae, and they are formed into a randomly oriented mat that is compressed into a thin wood web that can be a corrugated web or a flat web that is permanently set in a single press operation.
