Tensile Properties Prediction of Natural Fibers Metal Laminates FMLs

Abstract: Fiber–metal laminates (FMLs) are high-performance hybrid structures based on alternating stacked arrangements of fiber-reinforced plastic (FRP) plies and metal alloy layers FMLs have benefits over both aluminum and fiber reinforced composites. In this work, a jute fibers and effect of fiberFE volume fraction on tensile behavior of this novel material is investigated. A numerical simulation method based on finite element modeling (FEM) is used to predict the tensile proprerties of FMLs and compared with a result obtained by a modified classical laminate theory (CLT) given in literature. Good agreement is obtained between the models predictions and mathematical results. The obtained results show that the fiber volume fraction improves elastic and plastic moduli, yield stress and ultimate tensile stress considerably. Statistical analysis of data is done and an estimated tensile strength of each FMLs as a function of fiber volume fraction is obtaine
