Abstract

Influence of annealing treatment on adhesion behavior of poly(butylene terephthalate) (PBT) with epoxy adhesive was studied. The tensile adhesion strength decreased after the annealing treatment of PBT. In the case of the untreated PBT, the failure depth after the failure was not clearly defined. Once the PBT was annealed, the average failure depth turned to be 4 nm. The above results imply that the failure mechanism for the system transformed from interfacial failure to cohesive fracture upon annealing treatment. This can be easily understood by taking into account that a mechanically weak layer is formed in the surface region of PBT after the annealing. Such a weak boundary layer was observed by grazing incidence X-ray diffraction measurement.
