Abstract
Natural fiber Composites have low density & are bio-degradable along with easy handling & disposal as compared to synthetic fibers like glass, carbon, Kevlar etc. Research in this area may assist ease in design and efficient application of natural fibers. With this aim finite element modeling of natural plant and animal fiber reinforced polymeric hybrid composites is attempted here using Ansys® Composite Prepost (ACP) module of workbench 18.2. Woven jute fabric was initially modelled as a unit woven cell (2 * 2 yarn) in Texgen® and the subsequent elastic constants were calculated through Abaqus® using cdmHUB®. Weight fractions of fibers and matrix were converted into respective volume fractions for calculation of relative constituent thickness in the FEM model of ACP. Tensile, compressive and flexural strengths for ASTM D638, ASTM D695 and ASTM D 790 are calculated and compared with experimental values with an average variation of 3.78%. FEM model is successfully checked for validation at volume fraction value slightly less and more than that of maximum strength. In terms of reducing overall density of polymeric hybrid composite, the chicken feather fiber is seen having significant effect, whereas jute fiber improves mechanical properties like tensile strength, compressive strength and flexural strength significantly.
