Application of chemiluminescence and isoconversional kinetics for the prediction of organic materials.
Adhesives are increasingly being used to bond materials, even where mechanical bonds were previously used. This is due to a need for lightweight structures and the introduction of novel materials. However, some users are skeptical about adhesive bonds for constructions with long life cycles, such as building fronts or load-bearing elements.
There is an almost unlimited manifold of mechanisms that lead to the failure of adhesive bonds (Scheme 1). Bond rupture can occur in adhesion or cohesion zones. Mechanical or chemical stress (or both) can cause bond failure. The last case seems to occur most often in a non-linear time dependency for the process of bond rupture.
