This study investigates impact behavior and energy absorption of a Fiber Metal Laminate (FML) made of ultra-high molecular weight polyethylene (UHMWPE) fiber composite and aluminum 2024-T3 sheets. Specimens have been tested against two types of projectiles and failure modes are compared. The effect of different thicknesses of aluminum sheets and composite core on impact performance is investigated. To examine the influence of the lay-up sequence, two types of FML including 2/1 and 3/2 configurations have been tested. The results show that increasing the thickness of the composite core increases the absorption of energy as well as specific energy absorption (SEA). The highest amount of SEA is obtained for the sample with the lowest metal volume fraction. Damage patterns show that due to the flexibility of UHMWPE fibers and ductility of Al 2024-T3, the metal and the composite core have been deformed proportionally and more energy is absorbed. This mechanism is not seen in other conventional FMLs such as glass fiber metal laminate (GLARE). Compared with aluminum sheet and GLARE under the same conditions, the proposed FML has SEA more than 3 times that of aluminum and more than 2 times that of GLARE.

The combat vehicles that Indonesia Army belong to most of the materials are steel, for example the armored vehicle anoa 6x6. Steel material is used as a fire protection on the vehicle, it will greatly affect the performance of the vehicle. It is caused the steel material has a high density, which is around 7750 kg/m3to 8050 kg/m3. So, with a large enough volume of the vehicle body, it will increase the burden of the vehicle. As well as the engine load will increase, and more power is needed to be able to move the vehicle. Seeing these problems, it is necessary to have a research or study on alternative materials to replace the body of a combat vehicle that can withstand fire from opposing weapons that cause personnel to be injured. In this study, experimental and simulation methods were used using the ansys application to analyze the strength of the composite material in the form of an aluminum layer that had been treated to increase the hardness value. Furthermore, it is coated with a composite material using a carbon fiber matrix of epoxy, HGM and polyurethane. The coating material is called Fiber Metal Laminate (FML), so the material used has a lighter density, the load received by the vehicle engine is lighter, and the performance of the vehicle will be more effective and efficient.
