Abstract
Official abstract text for this publication.
The general inventive concepts relate to engineered wood products. The engineered wood products demonstrate improved properties including acoustic damping, fire resistance, and water absorption relative to similar engineered wood products that comprise only a single source of fibers. In contrast, the inventive engineered wood products include a combination of at least two types of fibers.
First claim
Opening claim text (preview).
What is claimed is: 1. An engineered wood product comprising fibrous materials in an amount of 80% to 98% by weight of the engineered wood product, and a binder, wherein the fibrous materials comprise: glass fibers in an amount of 1% to 60% by weight of the fibrous material, and wood fibers; and wherein the binder is selected from a urea-formaldehyde binder present in an amount of 5% to 20% by weight of the engineered wood product and a MDI binder present in an amount of 2% to 7% by weight of the engineered wood product. 2. The engineered wood product of claim 1 , wherein the glass fibers have an average diameter of 0.5 microns to 350 microns. 3. The engineered wood product of claim 1 , wherein the glass fibers have an average length of 2 microns to 25 millimeters. 4. The engineered wood product of claim 1 , wherein the engineered wood product is in the form of a high-density board.
