A structural material consisting of sheets of wood glued or cemented together with the grains of adjacent layers arranged at right angles or at a wide angle.<br> Wood is a structural tissue found in the stems and roots of trees and other woody plants. It is an organic material – a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression.<br> Hardboard is made from pulped wood fibers that are compressed under heat into thin sheets, without the use of glue, and is also known as high-density fiber board. The fibers can come from forest and wood waste, and recycled wood materials
