Abstract

During the past decades, the increasing demand of high performance and lightweight materials has stimulated the development of alternative materials, namely Fibre Metal Laminate (FML) structures. FML is a sandwich structure which is formed by bonding the metallic layers with composite as core constituent by means of adhesive agent. In this study, the mechanical behaviour of FMLs with the core constituents of environmental friendly kenaf fibre reinforced polypropylene composites was studied. The FMLs were manufactured through the hot press moulding compression method where the adhesives were incorporated between metallic layers and composite. The effects of fibre compositions (50, 60, and 70 wt%), fibre lengths (30, 60, 90 mm) and chemical treatment on the mechanical responses of FML were investigated. Results revealed that the increase of fibre composition and fibre length reduces the mechanical strength of FML. Highest tensile strength of FMLs is 46.70MPa which is 50wt% with 60mm fibre length while highest flexural strength of FMLs is 86.36MPa which is 50wt% with 90mm fibre length. However, the chemical treated kenaf fibre reinforced FML showed a significant enhancement of 10% to 20% on the mechanical properties in comparison to the non-treated fibre reinforced FML.
