“…Analytical results are also compared with numerical results and good agreement is found. In the authors' previous studies, it was found that the synthetic fiber reinforced composite longitudinal modulus (E 1 ) is not affected by deboning defects and moisture defects [ 24 , 41 ], but the behavior of the NF is different when compared to natural fiber. The HS of the NF has a considerable influence on the E 1 .…”

“…A solid 186 element has been used to describe the model generated for the analysis. This solid 186 is defined by 20 nodes, and each node possesses three directional freedoms, i.e., in the X, Y, and Z directions [ 41 ]. Converged FE models are used for the analysis.…”

“…For that, the nodes corresponding to the X = 0, Y = 0, and Z = 0 areas are arrested to move in the X, Y, and Z directions, respectively. Multipoint constraints are applied to the corresponding nodes of the FE model in the positive directions [ 41 , 42 ]. The longitudinal modulus is obtained by applying uniform pressure parallel to the fiber (Z axis) and, using Hooks’ law, the longitudinal modulus is obtained ( Figure 3 a).…”

A two-stage micromechanics technique is used to predict the elastic modulus, as well as the major and minor Poisson’s ratio of unidirectional natural fiber (NF) reinforced composites. The actual NF microstructure consists of cellulose, hemicellulose, lignin, lumen, etc., and these constituents and their contributions are neglected in classical models while quantifying their mechanical properties. The present paper addresses the effect of the real microstructure of the natural jute fiber (JF) by applying a micromechanics approach with the Finite Element Method. Six different hierarchically micro-structured JFs are considered to quantify the JF elastic properties in the first level of homogenization. Later, the JF reinforced polypropylene matrix properties are investigated in the second stage by adopting a homogenization approach. Taking into account the different hierarchical structures (HS), the fiber direction modulus (E1), transverse modulus (E2 and E3), in-plane and out-of-plane shear modulus (G12 and G23), and major (ν12, ν13) and minor (ν23, ν21) Poisson’s ratios are estimated for JF and JF reinforced polypropylene composites. The predicted elastic modulus from micromechanics models is validated against the analytical results and experimental predictions. From the present work, it is observed that the HS of NF needs to be considered while addressing the elastic properties of the NF-reinforced composite for their effective design, particularly at a higher volume fraction of NF.

“…The volume fraction of fiber is changed from 10 to 50%. The Young's modulus of an epoxy matrix is 5.171 GPa, Poisson's ratio (ν) 0.35, sisal fiber modulus 190GPa, Poisson's ratio of sisal fiber 0.3 [20][21]27]. The carbon nanotube mixed sisal fiber reinforced epoxycomposite elastic properties are obtained from our previous research work [28].…”
