Fibre Metal Laminate (FML) is hybrid material that has the combined advantages of metallic materials and fibre reinforced matrix. It has been widely used in the aircraft industry for impact prone applications due to its excellent fatigue and impact resistance. This research focuses on the quasi-static indentation behaviour of fibre metal laminates based on NaOH treated and untreated kenaf bast fibre with fibre loading wt% of 50, 60 and 70 and fibre length in cm of 3, 6 and 9. Aluminium 5052-O has been used as the skin layers of FML in this study. Hot compression moulding method has been used to fabricate the composite and FML panels for this study. The prepared specimens were tested in accordance with ASTM D 6264 using Instron 5585 universal testing machine to assess their quasi-static indentation performance. The results revealed that treated FMLT-60(9) with fibre loading 60wt% and fibre length of 9cm exhibited the highest energy absorption at 30.82 J.
