Mechanical Characterization and Finite Element Investigation on Properties of PLA-Jute Composite

Abstract

materials are on high demand in recent days amongst high performance products that need to be strong enough in severe loading conditions. It can be developed with a suitable combination of matrix and reinforcement materials to meet the requirement of specific applications. The present work attempts to form composite plates using a combination of natural polymers and fibers to improve certain properties. The focus is to develop a biodegradable composite of comparable properties with those available commercially. The formed plates are tested to determine different mechanical properties such as tensile strength, impact resistance, hardness etc. The thermal parameters are also determined by DSC (Differential scanning calorimetry) test. A finite element analysis is conducted and the results have been compared with Graphite epoxy composite for checking the effective use of this material. responses along with vibration behavior of laminated composite plates have been extensively investigated. Pandya and Kant (6) has proposed a C0 continuous displacement finite element formulation of laminated composite plates under transverse loading using Higher order Shear Deformation theory. The static behavior of laminated composite and sandwich plates is studied analytically using Navier's technique based on higher order refined theory by Kant and Swaminathan (7). Soltani et al. (8) has analyzed nonlinear tensile behavior of glass fibre reinforced aluminium laminates using finite element modeling. Attallah et al. (9) presented 3- D solutions of laminated composite plates by using a combined finite strip and state space approach. Bharet al. (10) analyzed the significance of the HSDT over the FSDT for laminated composite stiffened plates by using FEM. Grover et al. (11) investigated the static and buckling analysis of laminated composite and sandwich plates in the framework of a new inverse hyperbolic shear deformation theory and this theory is based on shear strain shape function. Kumar et al. (12) studied static analysis of thick skew laminated composite plate with elliptical cutout based on 3-D elasticity theories. Riyah and Ahmed (13 investigated stresses of composite plates with different types of cutouts. Rezaeepazhand and Jafari (14) analytically analyzed the stresses of composite plates with a quasi-square cutout subjected to uniaxial tension based on Lekhnitskii's theory. Static analysis of isotropic rectangular plate with various support conditions and loads are studied by Vanamet al. (15) using finite element analysis (FEA). A recent study detailed the effect of cutout orientation on SCF (16).
