Plywood is a three-layer or multi-layer board like material made by rotating and cutting wood segments into veneer or planing wood into thin wood, and then bonding with adhesive. It is usually made of odd layer veneer, and the fiber directions of adjacent layers of veneer are perpendicular to each other.
Plywood is one of the commonly used materials for furniture, one of the three major artificial boards, and can also be used as a material for airplanes, ships, trains, automobiles, buildings, and packaging boxes. A group of veneers is usually formed by gluing adjacent layers of wood grain perpendicular to each other, with the surface and inner layers symmetrically arranged on both sides of the central layer or core. A slab made by interlacing the glued veneer in the direction of the wood grain and pressing it under heating or non heating conditions. The number of layers is generally odd, and a few may have even numbers. The differences in physical and mechanical properties in the vertical and horizontal directions are relatively small. The commonly used types of plywood include plywood, plywood, etc. Plywood can improve wood utilization and is a major way to save wood.
