Abstract

The growing concerns in reducing the usage of non-renewable sources in production of engineering materials have called for the development of FML. Fibre Metal Laminate (FML) is hybrid material that has the combined advantages of metallic materials and fibre reinforced matrix systems. It had been widely used in aircraft and automotive industry for impact prone applications due to its excellent mechanical properties. This study investigates the quasi static indentation behaviour of fibre metal laminates (FML) based on kenaf/Poypropylene. The effects of fibre length (3, 6 and 9cm) and fibre loading (50, 60 and 70 wt%) were studied. Aluminium 5052-0 has been used in this research. The specimens were prepared and tested using Instron Universal Mechanical Tester 5585H in accordance to ASTM D6264 to assess their performance. The results reveal that FML 60 wt% treated 9cm kenaf fibre exhibited the highest energy absorbing properties at 30.82J compared to other configuration tested. It also proves that FMLs with treated kenaf fibre absorbs an average of 19% more energy compared to FMLs with untreated kenaf fibre.
