Abstract
This paper examines the interfacial shear properties of a new fiber metal laminates based on oil palm fiber reinforced polypropylene. The adhesive shear strength based on two type of surface treatment technique had been studied to determine the best technique to ensure a good bonding for fiber metal laminates based on oil palm empty fruit bunch fiber reinforced polypropylene (EFB pp) composite and aluminium 6061. Adhesion between aluminum and EFB pp composite was achieved by incorporating modified polypropylene adhesive film and surface treatment of Al sheets. Differential Scanning Calorimetry test showed the suitable bonding temperature between the composite and glue to be between 140°C to 155°C which is lower than the melting temperature of polypropylene. The applied surface treatment of ethanol solvent wipe and NaOH chemical etch though have effect on the surface roughness but have no significant effect on the maximum adhesion shear stress. The modified polypropylene adhesive film selected for this work is suitable to bond EFB pp composite with aluminium 6061 and both surface treatment is equally suitable.
