Abstract

In this work, we studied the effect of surface treatment of the aluminium surface and a coupling agent to improve adhesion between aluminium with organic polymer. Thermoplastic natural rubber (TPNR) matrix was prepared by melt blending of natural rubber (NR), liquid natural rubber (LNR) as a compatibilizer, linear low density polyethylene (LLDPE) and polyethylene grafted maleic anhydride (PE-g-MAH) as a coupling agent. The PEgMAH concentration used was varied from 0 to 20%. In addition, the aluminium surface was pre-treated with 3-glycidoxy propyl trimethoxy silane (3-GPS) to enhance the mechanical properties of laminated composite. It was found that the shear strength of the single lap joint Al-TPNR laminated composite showing an increasing trend as a function of PE-g- MAH contents for the 3-GPS surface treated aluminium. Moreover, the FTIR-ATR, XPS and SEM analysis revealed that the strength improvement was associated to the chemical state of the compound involved.
