Adhesives with wood materials : bond formation and performance

Abstract

Adhesive bonding of wood plays an increasing role in the forest products industry and is a key factor for efficiently utilizing our timber resource. The main use of adhesives is in the manufacture of building materials, including plywood, oriented strandboard, particleboard, fiberboard, structural composite lumber, doors, windows and frames, and factory-laminated wood products. Adhesives are also used in the assembly of furniture and cabinets, manufacture of engineered wood products, and construction of residential and commercial structures. Adhesives transfer and distribute loads between components, thereby increasing the strength and stiffness of wood products. Effective transfer of stress from one member to another depends on the strength of the links in an imaginary chain across the adhesive-bonded joint (Fig. 10–1). Thus, the performance of a bonded joint depends on how well the complex factors that contribute to the properties of the individual links (wood, adhesive, and interphase regions of wood and adhesive) are controlled during product assembly, which ultimately determines the strength of the chain.
