Vibration Characteristics of Composite Beam Having Flax, Aloevera and Sisal Fibers as Reinforcements

Abstract

Composites are highly significant due to their various advantages and natural fibre reinforced composites can be vastly used in automobile and aircraft interior applications. This paper principally deals with natural fibre reinforced composite (NFC) in which flax, aloevera, sisal fibres are selected to be reinforced in epoxy matrix (as inner laminate layers) and is used in combination with glass-epoxy (as outer laminate layers). Such composite beam structures are analysed in Ansys software employing FEM. The comparison for various NFCs is presented by evaluating effect on natural frequency due to various parametric variations like laminate stacking sequence, material hybridization, and presence of cut out.
