Description: Wood is a complex and heterogeneous material, exhibiting variation in its structure and properties at all size scales. For furniture manufacturing, both macro- and microscopic variations in wood structure affect its bondability with various adhesives and the longevity of those bonds. For example, the relative proportion of earlywood and latewood affect mechanical and rheological properties of wood and dimensional stability and is an important macroscopic feature. Especially in some hardwoods, microscopic characteristics such as vessel size and their distribution influence minimum thickness of the veneer or adhesive formulation to minimize bleed through. At a larger size scale, the presence of juvenile wood or reaction wood in a piece of core stock affect mechanical and physical properties of the wood, thus potentially changing the expected efficacy of bonding and durability of these bonds. The substitution of plantation-grown wood for old-growth wood complicates the performance of these bonds by decreasing uniformity of wood properties. In summary, variations in chemical composition and micro- and macroscopic wood structure play important roles in bonding wood. Understanding these factors is the first step toward achieving good service life for furniture and structural wood applications.
