Plywood is a material manufactured from thin layers or “plies” of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which includes medium-density fibreboard (MDF) and particle board (chipboard).
The most commonly used thickness range is from 1?8 to 3.0 inches (3.2 to 76.2 mm). The sizes of the most commonly used plywood sheets are 4 x 8 feet (1220 x 2440 mm) which was first used by the Portland Manufacturing Company, who developed what we know of as modern veneer core plywood for the 1905 Portland World Fair. A common metric size for a sheet of plywood is 1200 x 2400 mm. 5 × 5 feet (1,500 × 1,500 mm) is also a common European size for Baltic birch ply, and aircraft ply.
Sizes on specialised plywood for concrete-forming can range from 15?64 to 13?16 in (6 to 21 mm), and a multitude of formats exist, though 15 × 750 × 1,500 mm (.59in × 30 × 59 in) (19/32in × 2 ft-6in × 4 ft-11in) is very commonly used.
Aircraft plywood is available in thicknesses of 1?8 inch (3 mm) (3 ply construction) and upwards; typically aircraft plywood uses veneers of 0.5 mm (approx 1/64 in) thickness although much thinner veneers such as 0.1 mm are also used in construction of some of the thinner panels.
All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called cross-graining and has several important benefits: it reduces the tendency of wood to split when nailed in at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite parts, it has high stiffness perpendicular to the grain direction of the surface ply.
Smaller, thinner, and lower-quality plywoods may only have their plies (layers) arranged at right angles to each other. Some better-quality plywood products will by design have five plies in steps of 45 degrees (0, 45, 90, 135, and 180 degrees), giving strength in multiple axes.
