Carbon fibre reinforced aluminium laminates (CRALL) are a kind of fibre-metal laminates (FMLs) materials combining the excellent impact resistance of metallic materials with the good fatigue behaviour of fibre reinforced polymeric (FRP) materials. FMLs are an advanced hybrid materials system being evaluated as a damage tolerance and light weight solution for aircraft primary structures due to their increased stiffness and strength in comparison to aluminium. The impact response of fibre-metal laminates, in particular, formed by imbedding glass and aramid fibre in aluminium laminates (GLARE and ARALL), have received much attention from recent experimental studies and are presently being employed in aviation applications [1, 2]. Examples such as GLARE panels in the upper fuselage of the Airbus A380 commercial aircraft and ARALL panels to be used as material for the highly fatigue rear cargo door of the C-17 cargo door to reduce overall weight [3, 4]. In fact, sufficient experimental data have been generated, demonstrating the superior fatigue performance and impact resistance of GLARE compared to monolithic aluminium alloys [5-8]. In the alternatives, researches on the impact behaviour of the CFRP and CRALL have been performed mainly in static and low velocity regimes (<10 m/s). Till now, insufficient experimental results can be found in literatures that described in detail in the impact resistance of CFRP and CRALLs for high velocity regimes (>100 m/s). One probable reason may be due to the poor damage resistance of CFRP and CRALL in the low energy drop weight tests [6], other reasons probably due to the cost of high velocity investigations and measuring difficulty.
