A Study on the Influence of Nanofillers on the Vibrational Characteristics of Fiber Metal Laminates

In the last several years, there has been a discernible increase in research devoted to developing innovative and complex composite materials. Because of their superior performance, especially in the aircraft industry, Fibre Metal Laminates (FML) and hybrid structures made of glass, aramid fibre, carbon, or aluminium are the most commonly used of these new technological commodities. Thus, free vibration analysis is the first step in the design of these structures. The current work examines the vibration behavior of a fiber-metal-laminate (FML) composite beam using numerical and experimental methods, a novel material for aircraft. This research series evaluated the bending natural vibration frequencies of the multi-walled carbon nanotube FML composite cantilevered beam. The Bruel and Kjaer (B and K) Fast Fourier Transform (FFT) analyzer with a PULSE platform was used in this study to find the intrinsic vibration frequencies of glass FML beams. Two parameters that investigated the dynamic behavior of the FML composite beam were the amount of MWCNT filler material and the beam's length. There was a reasonable agreement between the experimental and numerical results and the natural frequencies. The amount of MWCNT filler added to the glass fiber epoxy enhances the natural frequency of the FML composite cantilevered beam, according to both experimental and computational calculations. Furthermore, it was discovered that the vibration's inherent bending frequency decreases with the beam length.
