Abstract

The free vibration and bending characteristics of hybrid jute composite beams are examined in the current paper using the finite element method (FEM). The hybrid jute composite beam contains jute fiber and glass fiber reinforced polymer composites. The hybrid composites are manufactured via a vacuum-assisted hand layup method. Experimental vibration analysis was performed on composite beams to predict natural frequencies under cantilever end conditions. The higher order theory based finite element formulation was developed and are solved using MATLAB® software to obtain the natural frequencies of the jute and hybrid jute composite beams. The validity of the FEM results (natural frequency, deflection and stress) is compared with the literature, and it shows very good agreement for composites. This study also examines the impact of stacking order, end condition, and ply orientation on the vibration and bending properties of hybrid jute composite beams.
