Major Features of Plywood - Essay Example

The wood grains of adjacent plies are up to 900 in rotation. Ply woods can have different numbers of plies glued together. Typically, the number of plies is odd, such as three, five, and seven. For example, a three-ply piece has three veneers glued together while a five fly piece has five veneers glued together. Generally, plywood is considered to be composites given that they are made of at least two materials; fiber sheets and glue (Logan, 2014).

There are different types of plywood, each suited to a particular use. Some of the most common types of plywood include softwood, hardwood, tropical, aircraft, and special-purpose. Although they are commonly used in (building) construction, plywood also finds use in boats, furniture, vehicle internal body works, and packages (Ernes, 1970). The core layers of plywood serve to increase the distance between the outer layers so that the material can accommodate more bending stresses.
