Basic Principles Of Plywood
In order to improve the anisotropic properties of natural wood as much as possible, and make the plywood have uniform characteristics and stable shape, generally plywood must comply with two basic principles in structure: one is symmetry; the other is that the fibers of adjacent layers of veneer are perpendicular to each other. The principle of symmetry requires that the veneers on both sides of the center plane of symmetry of the plywood should be symmetrical to each other regardless
