Armored Vehicle

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.

Simulating the vehicle collision has gained importance in the automotive sector due to its accuracy, cost effectiveness and enhanced reliability. It aids in improving the safety of driver and passenger and also examine the cause of crash or collision. This numerical analysis investigates the materials capability to enhance safety. A three-dimensional vehicle model was developed along with its roll cage using solid work tool. Hypermesh work bench was employed to discretise the sensitive parts of the body and roll cage using beam 189 element having six degree of freedom at each node. The existing structural steel members were replaced with reinforced carbon fibre in all the sensitive part of the body and roll cage and its structural stability was assessed using the frontal, side and roll over crash simulation using LS Dyna. This investigation also reveals the change in internal energy, kinetic energy absorption and momentum transfer for both structural steel and carbon fiber under all the crash scenarios. The outcomes of this numerical investigation proved that the reinforced carbon fiber can be effectively replaced with the structural steel to enhance safety.

The V-die bending of a carbon-fiber-reinforced thermoplastic laminate bonded to thin cover layers made of microalloyed steel was investigated. Such hybrid semifinished products are gaining importance in transport-related lightweight designs. Experiments were conducted for different forming temperatures and dwell times to determine suitable process parameters. The punch radius was varied to evaluate its influence on the springback/negative springback of the fiber–metal laminate (FML). The results, which are in good accordance with a simple analytical model, showed that the solidification of the composite core can compensate for the springback of the metal layers. Micrographs further revealed that the fiber orientation can affect the thickness distribution in the bend area.

The Fiber Metal Laminates (FMLs) was studied and improved the mechanical properties were used for aircraft wing. The FMLs are consisting of metal sheets reinforced with fiber bonded by matrix phase. The FMLs consist of seven layers to produce the Hybrid composite materials that made from 2024-T3 Aluminuim sheets with carbon and glass fibers as reinforcement and bonded using adhesion materials that are locally manufactured from resole resin with adding using epoxy resin. By using the FMLs, the mechanical characteristics have been improved and the weight of the aircraft wing has been reduced. The mechanical characteristics have been improved comparing to other FMLs using commercial epoxy. The FMLs with carbon and glass fibers have high tensile strength and elastic modulus but low yield and elongation comparing with the FMLs of carbon fibers as a reinforcement. The flexural modulus and impact toughness is high for the FMLs with glass fiber comparing with jute fibers with adding using carbon fiber as areinforcement.The Aramid Reinforced Aluminum Laminates (ARALLs) have low fatigue strength than FMLs using carbon fiber as reinforcement. The FMLs are lower ratio of ultimate to yield strength and density than 2024-T3 Aluminum alloy that commonly used in aircraft wing.

AbstractVacuum infusion is a method of making composite materials by using a vacuum pump to drain and spread the resin in molding. Vacuum infusion can strengthen the mechanical properties of a composite material because the manufacturing process is given a negative pressure which makes the resin or matrix permeate better than the hand lay-up method. Vacuum infusion composites can be used as the main ingredient of a vehicle body due to its strong, flexible nature in its form and manufacture so that it can be shaped as desired. This study examines the effect of vacuum pump pressure on two mechanical properties (impact and bending) of a carbon fiber composite material given an epoxy matrix. The results of this study get an increase in strength of mechanical properties with added vacuum pump pressure.Keywords : carbon fiber, composite, increase in strength, mechanical properties, Vacuum Infusion, vacuum pump pressure.

In this paper, the failure behavior of fiber–metal laminate patches as a repair system for steel transmission lines has been investigated and the results are compared with those of the other materials commonly used for repairing pipelines such as composite patches. The laboratory test is also employed to experimentally estimate the pipe burst pressure for the tubes made of API A106 Grade B steel. A comparison of the results using different fiber–metal laminates patches and composite is made. As fillers, putties with two different elastic constants are introduced. Also, taking the cohesive behavior of the patch into account in the numerical model, the effect of the patch on the failure pressures is evaluated. The failure parameter in different patch layers for various types of fiber–metal laminates made of GLARE and CARRALL has been investigated. For significant improvement in the failure behavior of fiber–metal laminate patches, carbon fiber layers are used. Also, to prevent corrosion effects between aluminum and carbon fibers, a combination of aluminum, glass fiber reinforced polymer, and carbon fiber reinforced polymer is utilized. Moreover, the damage behavior of steel pipe and aluminum layers in the fiber–metal laminate patch has been numerically described. The results obtained in the present work clearly show the superior advantage of fiber–metal laminate patches over the conventional composite ones. Experimental results lead to the fact that internal pressure corresponding to final layer failure in composite patches and first layer failure in fiber–metal laminate patches should be considered as a reliable estimation to predict the final burst pressure.
