摘要：The present invention is a resin-starved pultruded-impregnated panel, wood composites utilizing said panel, and a method of making the same. The panel of the present invention comprises a pultruded center portion made from a plurality of fibers bound together by a resin such that the surfaces of the center portion contain significantly less resin than the core, and a layer of an impregnating adhesive, having similar chemical properties to chemical properties of a bonding adhesive used to laminate layers of the wood composite, bonded to each surface to form the surfaces of the panel. The wood composite of the present invention comprises a plurality of wooden members disposed in substantially parallel relation to one another, at least one resin starved pultruded panel disposed at a predetermined location between two of the members; and a bonding adhesive disposed between the surfaces of the members the panel to bond them together. The method of the present invention comprises the steps of forming a resin starved pultruded impregnated panel by forming a pultruded center portion having a pair of resin starved surfaces, impregnating the surfaces with an impregnating adhesive, removing a portion of the impregnating adhesive to form a substantially smooth flat surface, and curing the remaining adhesive, disposing the panel between at least two wooden members, and bonding the panel and wooden members together to form a wood composite.
