2.1 Notions of adhesion and cohesion
A distinction must be made between adhesion and cohesion (figure 4 ). The strength of a bonded assembly depends directly on :
the internal cohesive force of the adhesive ;
compatibility between adhesive and substrates, the ability of the adhesive to wet the surfaces of each substrate;
the internal cohesive forces of the substrates.
Adhesion (expressed in N/m) depends on the nature of the adhesive, the nature of the substrates (more or less easy to bond depending on surface energy) and time (rise in adhesive performance)....
