Plywood is one of the commonly used materials for building and furniture. It is one of the three wood-based panels. It can also be used for aircraft, ships, trains, cars, construction and packaging. A group of veneers are usually bonded vertically to each other in the direction of the wood grain of adjacent layers. Generally, the veneer and the inner panel are symmetrically equipped at the center layer or the two ends of the core. The slab, which is made of glued veneer interlaced in the direction of wood grain, is bound under heating or unheating conditions. The number of layers is odd and even even. The physical and mechanical properties of longitudinal and transverse directions are relatively small. Where are the plywood used for construction?
