Natural fibres with strong mechanical characteristics that are utilized as the reinforcing phase in natural fibre-based composites can withstand a wide range of vibrations while in service. The modal and harmonic analysis of natural fibre reinforced epoxy composites were performed to study the structural behaviour of composites with the onset of loading which can aid in identifying realistic potential applications in the field of vibration isolation, impact energy absorption and in fabrication of super-light composite panels. The effect of varying the fibre volume fraction on vibrational properties has also been investigated. The elastic characteristics were obtained analytically, whereas the frequency investigations were carried out using finite element modeling. Further-more, frequency response function (FRF) bode plots for different fibres were observed and examined in relation to various parameters. It was found that volume percentage and plate aspect ratio had a substantial impact on frequency. Lower frequencies might result in more fatigue damage to the composites.
