Tensile stress–strain behaviour of a structural bonding tape

This is the authors' abstract. We don't add key points for this paper.

The tensile properties of a pressure-sensitive adhesive tape which can be cured to impart structural performance have been measured at different temperatures using quasi-static tests. In order to assess the linear viscoelastic behaviour of the tape, results from the vibrating beam technique are also presented. Bulk specimens and non-contacting extensometers were found to be suitable for tensile measurements on such a flexible adhesive. The results show that the strength of the tape is not as high as, and that its behaviour is very different from, traditional structural adhesives, but its high strain-to-failure with an adequate strength offers exciting possibilities for structural joints.
