Abstract: This review article focused to highlight the recent studies conducted to explore the dynamics characteristics of fibre-reinforced composite via. experimental and numerical approaches for different volume ratios analysed for various boundary conditions. Because of the benefits in performance, structural efficiency, and cost that improved composite materials give, they are progressively being used in aircraft, marine, and other industries. The vibration effect in most of the applications is unpleasant causing user discomfort, noise, bodily health problems, and structural endurance problems. It is necessary to understand dynamic characteristics viz., natural frequencies (ω_n), damping characteristics (C), and frequency response function (FRF) of the beam. This article focused on various fabrication technologies utilised in the manufacturing of aramid fibre composite beams. Based on the available literature polymerisation induced self-assembly fabrication technique used to produce the aramid fibre and FFT analyser is widely used to analyse the dynamic characteristics of the beam structure.

Keywords: aramid fibre; natural frequencies; damping characteristics; frequency response function; FRF.
