AbstractThe use of fiber-metal laminates (FML) allows for substantial advantages over a fuselage skin made of monolithic aluminum materials. Glass fiber prepreg reinforced aluminium is characterized by high damage tolerance capabilities, supporting the structural strength capability in case of any kind of damage. For this reason, FML, and GLARE in particular, have been identified as superior materials for aerospace applications. More than 400m2 FML is applied on each A380, as skin panels and as D-noses for both, vertical and horizontal stabilizer. FML possess the potential to become the baseline material for next-generation single-aisle aircrafts [1, 2, 6].The development of a new production chain that will allow automated fuselage production for future short-haul aircrafts is the focus of the studies that make up the joint project AUTOGLARE. As part of the fifth call-up for the German Aeronautical Research Programme (LuFo), the German Aerospace Center (DLR) is working with its project partners Airbus Operations, Premium Aerotech (PAG) and the Fraunhofer Gesellschaft (FhG). The development of a production chain for stiffened fuselage panels made of Fiber metal Laminates should support a production rate of 60 aircraft per month [3].This study contains the research work of the DLR and FhG regarding the automated and quality assured process for chain stiffened FML fuselages. In addition to a detailed explanation of the systems that were set up, this paper covers the planned tests, the completed demonstration models and the findings derived from them.


Materials having low density combined with superior strength are gaining demand in the field of automobiles, aeronautical and military appliances. Fiber Metal Laminates (FML) is becoming the material of choice for the above mentioned applications because of the ability to tailor it to meet the demands of the end applications. This paper throws light on the commercially available for of FMLs, its production methods, property enhancement and diverse applications. As such Carbon fibre reinforced composite are preferred for making automobile bonnets and fuselage in military aircraft due to the superior strength to weight ratio. On the other hand glass fiber reinforced composite materials are used to manufacture railway locomotive body panels due to the high tensile strength and impact strength. This paper can be used as reference for budding engineers who want to gain first-hand knowledge on FMLs.

In aviation industries, most of the stiffened structural components are manufactured by forming and laminating process. Combination of several conventional manufacturing processes is required in modern industries in hybrid laminate production. Fiber metal laminates undergo various joining process during assembly of aero-structures. Among them, forming and drilling are often required during assembly. Understanding the significance of various process parameters enables quality production and assembly of fiber metal laminates structures. Many researchers explored the cause and effect of few parameters and mechanisms which significantly alter the quality of form and drill. This review describes the progress in forming and drilling of fiber metal laminates for aerospace applications. Especially towards the process parameters, defects and their causes along with the preferred solutions recommended by the researcher society in forming and drilling processes. Numerous factors have controlled the quality of forming and drilling processes. Due to the machining parameters, different failure modes will occur in different layup of the laminates. To overcome the failures in machining/forming of fiber metal laminates, choosing the optimum parameter for the selection based procedure is needed to improve quality of fiber metal laminates.

Fiber Metal Laminates (FML) are a class of composites that are recently employed to substitute sole metals in various applications like aerospace applications. In this investigation, a new type of FML was successfully fabricated using compression moulding in which Aluminium and ceramics mat are stacked in the presence of epoxy resin. To improve the bonding by ensuring the flow of resin through the laminates, drilling with various pattern on the Aluminium sheet and ceramic mat were performed before subjected to compression to form FML. Aluminium sheets with Zig-zag pattern performed in a better way due to the improvements in bonding. In addition, drilling operation was done on the FML to ensure the de-lamination resistance and machinability. The drill bit before and after drilling was inspected by using optical microscope to understand the machinability behaviour of the FML.
