Complex dynamic moduli of Al/resin/Al sandwich bars were measured by the vibrating lead The influence of adhesive on the vibrational properties of the sandwich bars were studied in terms of temperature dependence of complex dynamic moduli. PVAc, PVC, PSt, PVAc/PVC, PVAc/PSt blend and cyanoacrylate adhesive were used for the material core of sandwich bars. The observed loss maximum of E'' of Al/PVAc/Al, Al/PVAc-PVC/Al and Al/PVAc-PSt/Al sandwich bars at 50℃ corresponded with the flow dispersion of PVAc. The observed loss peak of E'' of Al/PVAc-PSt/Al and Al/PSt/Al sandwich bars at 114℃ corresponded with the flow dispersion of PSt. The influence of flow dispersion of resin on the vibrational properties of the sandwich bars were larger than the dispersion of glass transition of resin.
