Plywood is one of the common furniture materials

Plywood is a kind of three or more layers of laminated material, which is made up of wood segments cut into veneers or planned into thin wood, then bonded with adhesives. Odd layers of veneers are usually used, and the fibers of adjacent layers of veneers are bonded vertically to each other.

Plywood is one of the common furniture materials. It is one of the three major wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packing boxes. A group of veneers are usually bonded vertically to each other in the direction of the adjacent wood grain. Usually, the surface and inner veneers are symmetrically arranged on both sides of the central layer or the core. Slab made of glued veneer interlaced vertically and horizontally in the direction of wood grain is pressed under heating or non-heating conditions. The number of layers is usually odd, and a few even. The difference of physical and mechanical properties between vertical and horizontal directions is small. The commonly used plywood types are three plywood and five plywood. Plywood can improve wood utilization rate, which is a main way to save wood.
