Factors affecting the adhesive force between metallic substrate and carbon black filled rubber composites

Abstract

This article is devoted to study the factors affecting the performance of the adhesively bonded joints between rubber composites and metal substrates. The mechanical strength of the adhesively bonded joint is assessed with regard to several parameters as the type of rubber, type and/or concentration of black fillers, type of adhesive system and type of metallic substrate. The mechanical properties of the adhesively bonded composites were measured under different modes of deformation such as the uniaxial extension, shear and peel tests. The results showed that the presence of black filler and/or polar group in the rubber composites enhanced adhesion effectiveness between the rubber composites and the metal substrate. This was confirmed by Fourier transformed infrared spectroscopic analysis and the swelling characteristics in benzene. Moreover, the two-component adhesive system was more effective in adhesion than the one-component adhesive. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
