摘要 The resin impregnated composite wood product comprises a plurality of wood layers, with each layer having relatively thin strips of wood. The strips in each layer are arranged at an angle to the strips of wood in adjacent layers. The strips of wood of such layers are saturated with resin throughout their length, width and thickness to fill the pores and when cured to provide a strong, tough, durable, long lasting product which is economical to manufacture.

What I claim is:1. The method of making a resin impregnated composite wood product from waste, scrap and used wood comprising the steps of:(a). using a power driven double edge blade to shave relatively thin strips of wood from logs, tops of logs, used lumber and other sources of scrap wood, with the strips of wood formed being of different lengths, widths and thicknesses;(b). grading the strips of wood as to length, width and thickness, with each strip having a length of twelve inches to ninety-six inches, a width of two inches to twelve inches and a thickness in the range of one-thirty second inch to three-sixteenth inch;(c). arranging on a support in rows strips of wood of different lengths, with the wood strips in each row being arranged end-to-end, while the wood strips in adjacent rows being side-by-side and different lengths to form a first layer of generally rectangular configuration;(d). applying a sufficient amount of a resin to the top surface of said first layer throughout its length and width which seeps through said first layer causing it to swell;(e). repeating step (c) to form a second layer of wood strips on the top surface of said first layer, with the wood strips of said second layer arranged at an angle to the wood strips of said first layer;(f). repeating step (d) by applying a sufficient amount of a resin to the top surface of said second layer which seeps through said second layer causing it to swell;(g). repeating steps (c) and (d), with the wood strips in each additional layer arranged at an angle to the wood strips in the preceding layer;(h). placing the resin impregnated wood layers in a press and subjecting the layers to pressure to thereby reduce the thickness of the layers to the required thickness of the wood product while the resin is being cured;(i). removing the resin cured wood layers from the press;(j). trimming the edges of the resin cured layers to remove irregularities from the peripheral surfaces; and(k). finishing one of the outer surfaces of the resin impregnate composite wood product.2. The method of making a resin impregnated composite wood product as defined in claim 1 comprising the steps of arranging each of the layers at an angle in the range of 20.degree. to 90.degree. with respect to the previous layer.3. The method of making a resin impregnated composite wood product as defined in claim 1 comprising the step of drying the wood strips prior to use to remove the moisture therefrom.4. The method of making a resin impregnated composite wood product as defined in claim 1 comprising the step of utilizing a brush for applying the resin to the several layers.5. The method of making a resin impregnated composite wood product as defined in claim 1 comprising the step of utilizing an airbrush for applying the resin to the several layers.6. The method of making a resin impregnated composite wood product as defined in claim 1 comprising the step of utilizing a drum sander to finish one or both of the outer surfaces of the wood layers.7. The method of making a resin impregnated composite wood product as defined in claim 1 comprising after the wood layers are removed from the press, the step of cutting the layers in desired lengths and widths to form panels, planks or blocks.8. The method of making a resin impregnated composite wood product as defined in claim 1 comprising the step of subjecting the layers to heat while in the press to assist in curing the resin as the pressure is applied.
