Determination of physical and mechanical properties of plywood produced using beech, okoume and ozigo species

Wood and wood-based materials are widely used in the construction industry world. The sustainable renewable nature of wood is seen as an important advantage contrast to non-renewable resources such aluminum, steel, concrete, plastic. In order protect advantages eliminate / reduce its disadvantages, plywood, particle board, fiber LVL, CLT, plastic composites etc. new engineering products produced. Plywoods automotive, construction, furniture, many industries. our country, plywoods produced using tropical species well native tree species. this study, density, water absorption, thickness swelling, bending resistance, elasticity modulus shear strength values plywood made beech, okoume ozigo investigated. Comparison from with beech has been made. It determined that higher density than plywood. observed there a linear relationship between strength, their full dry density.
