Reference work entry
Bonding (referred to as adhesive bonding) is a joining method that joins two or more materials by applying and solidifying adhesives.
Theory and Application
The adhesive bonding is a complex physical and chemical process that creates attractive forces between the substrates (base materials) and adhesive. As shown in Fig. 1, the adhesive bonded joint consists of three areas: cohesion, transition, and adhesion zone. In the cohesion zone, cohesive forces are a result of a number of molecular forces such as intermolecular interactions, mechanical bonds, or chemical bonds within the adhesive. The transition zone is an interphase boundary layer or inter-diffusion segment with nonuniform composition formed by interacting adhesive and the substrate surface. The thickness of the transition zone differs from nanometer to millimeter ranges. In the adhesion zone, adhesive forces are determined by various chemical, mechanical, and electrical interactions at the interfaces.
