Abstract
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.
Claims20
An engineered wood product comprising fibrous materials and a binder,
- wherein the fibrous materials are present in the engineered wood product in an amount of 80% to 98% by weight of the engineered wood product,
- wherein the fibrous materials comprise glass fibers and wood fibers in a weight ratio of 1:20 to 1:1 by weight of the fibrous material,
- 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.
A method of making an engineered wood product, the method comprising:
- mixing glass fibers and wood fibers in a weight ratio of 1:20 to 1:1;
- mixing a binder into the glass fibers and wood fibers to form a fibrous mixture;
- forming the fibrous mixture into the shape of a board;
- and
- curing the binder to form an engineered wood product.
