Studies on Aluminium Sheets Bonded by Ternary Blends of Poly(Vinyl Chloride),Epoxidised Natural Rubber and Carboxylated Nitrile Rubber with Respect to Dynamic Mechanical Properties and Adhesion Strength

Abstract

The peel strength of aluminium-aluminium joints bonded by an adhesive based on ternary 75/25/175 poly(vinyl chloride)/epoxidised natural rubber/carboxylated nitrile rubber blends was found to depend on moulding time. Dynamic mechanical studies of the Al-blend-Al composite structures provide useful information on adhesion. In addition, the composite structures were found to exhibit broad tan δ spectra from 0.093 to 0.411 over the temperature range from -2°C to 200°C. These composite structures may find use in various vibration isolation applications.
