Interface strength, work of adhesion and plasticity in the peel test
نویسندگان
چکیده
A cohesive zone model is proposed and analyzed for steady-state peeling of a thin rate-independent, elastic-plastic film bonded to an elastic substrate. A traction-separation description of the interface is embedded within continuum characterizations of the film and substrate. The primary parameters characterizing the tractionseparation relation are the work of adhesion and the peak separation stress, termed the interface strength. The objective of the study is the determination of the relationship of the peel force to the work of adhesion of the interface and its strength, with due regard for plastic deformation in the film. An example of an elastic film peeled from an elastic-plastic substrate is also presented.

The adhesion strength of a Cu/Cr/polyimide (PI) flexible copper clad laminate (FCCL), which was manufactured by the roll-to-roll process, was evaluated according to the thickness of the Cr seed layer using the 90 peel test. The changes in the morphology, chemical bonding and adhesion properties were characterized by scanning electron microscopy, atomic force microscopy and X-ray photoelectron s...
متن کاملAdhesion Strength Study of EVA Encapsulants on Glass Substrates
An extensive peel-test study was conducted to investigate the various factors that may affect the adhesion strength of photovoltaic module encapsulants, primarily ethylene-vinyl acetate (EVA), on glass substrates of various laminates based on a common configuration of glass/encapsulant/backfoil. The results show that "pure" or "absolute" adhesion strength of EVA-to-glass was very difficult to o...
