The present investigation deals with the prediction of tensile properties of a novel jute fiber based Fiber Metal Laminate (FML). Periodic Micromechanics is used to determine the orthotropic elastic properties of the fiber reinforced epoxy lamina, and the effect of fiber volume fraction on the tensile behavior of the FML is studied using FEM. The elastic and plastic Young's moduli and tensile yield strength of FMLs are determined by the curve fitting technique. The tensile strength obtained through this method is compared to that obtained by the analytical model available in the literature and a very good agreement is observed between the two. It is found that both the Young's moduli improve with an increase in the fiber volume fraction with a simultaneous increase in the tensile yield strength. Correlations for predicting the elastic and plastic Young's moduli as well as the tensile yield strength of the FMLs are also presented. Based on the observations of the present investigation, the FEM can be established to be an imperative tool for the study of the mechanical behavior of the FMLs. Keywords: Fiber Metal Laminates, Periodic micromechanics, FEM, ANSYS I.INTRODUCTION Fiber reinforced composites have replaced metals and alloys in most of the structural applications in the recent years. A more relevant and masterful materials that have recently evolved in the development of advanced composites are the Fiber Metal Laminates (FMLs). An FML tends to take advantage of ductility of engineering metals viz. aluminum, magnesium and their alloys and the high specific properties of fiber reinforced plastics resulting in the evolution of a material having properties superior to its constituents. The FMLs are known to possess excellent impact properties, good blunt notch and residual strengths, flame retardency and good manufacturability. The first commercial use of ARALL (Aramid Reinforced Aluminum Laminates) started in the year 1982 for aircraft wings applications. In the year 1987, another generation of these laminates with the trade name GLARE (Glass fiber Reinforced Aluminum Laminates) was put forth consisting of aluminum alloy sheets and unidirectional or bidirectional reinforced glass fiber/epoxy prepegs. GLARE and ARALL have been the most heavily researched FML till date. The structural performance of FMLs depends upon the stacking sequence, individual lamina properties, orientation of fibres in the lamina [1]. The need of shorter lead time in the manufacturing of composites and incorporating frequent changes in the geometrical properties viz. fiber orientation, stacking sequence and the lamina thicknesses of the laminates has pushed the designers to thrive for novel analytical as well as numerical methods for the same. Use of finite element analysis for the analysis of fiber-metallic laminates (FMLs) has gained tremendous relevance in recent years. Elasto-plastic behavior of an ARALL laminate in combination with the mechanical properties of aluminum and Kevlar was modeled through CLT by [2]. The tensile...

Multifunctionality and the demand for improving the properties of construction materials make it necessary to leave the approach of monomaterials and combine them to fabricate composite structures, such as combinations of metals with polymers. This article focuses on metal-polymer-metal sandwich sheets. Bonding is improved using adhesive layers. These sandwich sheets are designed for their mechanical and thermal properties, working capacity and so on. A short background of composites structures, to be used in the automotive and aerospace industry, is presented. Moreover, fabricating processes and forming methods for composites are briefly introduced. Finally, a study of 316L/polypropylene/316L sandwich sheets, manufactured in a roll-bonding process and heating press process, is introduced. Their mechanical behavior and formability by deep drawing are discussed. IntroductionAspects of environmental protection and recycling are becoming more and more important in our society and are the driving forces for development, especially in the area of aviation as well as automotive and transport. To fulfill the rising demands, ecological standards for new products can be a solution -for example, taking factors such as saving resources, sustainability and recycling as well as functionality, design and others into consideration. Novel materials with new and improved functions engender a high interest in the industrial community.Monomaterials of metals, ceramics or polymers cannot fulfill all the technological requirements for a variety of industrial applications. The activities in physics and chemistry as well as engineering are leading to materials with superior properties -often by combining monomaterials to hybrids. 1 Some industrially applied composite materials can be classified as follows: Sandwich composites are understood to be multilayered structures. By using these combinations, it is possible to 'tailor' the properties of special components by choosing the accurate combination of monomaterials, thus providing functionality to fulfill the qualified demands on modern materials and structures. 7 As defined by Zenkert, 8 they are a combination of materials with minimum one of higher strength to create a composite with selected lightweight properties. They are represented, principally, by fundamental patterns of two skin sheets, which are thin but of high strength and stiffness. These skins include a relatively thick, low-density core. These sandwich composites are widely used for engineering applications because of the extremely high stiffness-to-mass ratio.Sandwich materials can be formed with numerous skin (e.g. steel, aluminum alloy sheets etc.) and core materials (polymer foils or fiber-reinforced plastics (FRP), with polymer layers being homogenous or structured), and they are often bonded together using an adhesive agent. Because of being quite simple to manufacture using lamination, roll-bonding or heat-press joining processes as sketched in Figure 1, they exhibit a great potential for future use. 9,10 Moreove...

Producing structures, which have composite features (high strength and stiffness with low density) and metal properties (high toughness and deformability), was the idea, which resulted to introduce the fiber metal laminates (FMLs) as new advanced materials. [1] In these materials, the metals and composites can stick to each other by using polymeric adhesive agents. In most cases, the metals are used as the skins and the composites as the core of these structures. [2] The adhering can be done by the same used resin into the composite section or using another adhesive agent. The carbon-reinforced aluminum laminate (CARALL), [3] aramid-reinforced aluminum laminate (ARALL), [4] and glass laminate aluminum-reinforced epoxy (GLARE) [5] are the most favorable FMLs, which are reinforced by carbon, aramid, and glass fibers, respectively. Although these famous structures can respond to all mechanical properties, however, environmental issues like recycling these structures are one of the important limitations of FMLs.Although many attempts have been done to reduce these limitations, however, after recycling, most of the fibers lose their initial mechanical properties. [6] For this reason, other types of fibers like mineral or plant-based fibers have been developed to use in the composite core of FMLs. [7] One of the suitable fibers for this purpose can be basalt fibers. The comparison between the mechanical properties of basalt and glass fibers was done by Deák and Czigány. [8] The reported results in this work showed that tensile strength, elastic modulus, and strain at the breaking of basalt fibers (Kamenny Vek Co., Russia) were 2016 MPa, 61.9 GPa, and 3.56%, respectively, whereas these properties in glass fibers (Skoplast Ltd., Slovakia) were 1472 MPa, 57 GPa, and 2.71%, respectively. This shows that basalt fibers have higher mechanical properties than glass fibers. Also, the production costs of basalt fibers are lower than carbon fibers. [9] The higher thermal stability and environment friendliness are other features of basalt fibers. [10] Having these features encouraged the researchers to use these fibers in various novel FMLs. For example, Ferrante et al. [11] characterized the impact properties of basalt fibers/aluminum FML through a low-velocity impact test. In another interesting work, Medjahed et al. [12] fabricated the FML with the basalt fibers/phthalonitrile composite and an Al-Li alloy. Then, they characterized the mechanical and gamma-ray shielding performances of this FML.In the admirable work, Mottaghian et al. [13] used the FMLs as the skin of polyurethane-based sandwich panels to enhance the postbuckling performance of sandwich structures. It is worth noting that the hybrid basalt-glass fibers/epoxy composite as core and steel or magnesium metals as skins were used in these FMLs. Introducing basalt-flax fibers/titanium as a new kind of
