Geopolymeric Adhesives for Aluminium Joints

Abstract:

Article Preview

Bonded joints have been used in substitution of more traditional techniques as screws, rivets and mainly welding. However, the applications in which the work temperatures are relatively high remain as an obstacle to the use of more common polymeric adhesives. In this sense, the study of adhesive properties of thermally stable materials as the geopolymers becomes a need. This work deals with the adhesion of aluminium sandwich beams using geopolymeric adhesives. Metakaolin-based geopolymers were used as adhesives, activated with sodium and potassium silicates. Shear mode adhesion tests were accomplished and the results indicate the possibility for use of these new adhesives.
