In the present work, the vibration behavior of honeycomb cored multi‐walled carbon nanotube (MWCNT) and Ti3C2Tx‐MXene reinforced sandwich composite plate has been investigated. The elastic properties of two‐phase (Ti3C2Tx‐MXene‐MWCNT)/epoxy sandwich composite were evaluated by utilizing the Halpin‐Tsai method. Then, glass fiber was incorporated as reinforcement, and the elastic characteristics of the hybridized three phase composite were obtained using the Chamis analytical model. The vibration behavior of sandwich panels was investigated with the help of finite element formulation by obtaining the strain fields using high‐order shear deformation theory. The developed numerical model was experimentally validated, demonstrating its efficacy in predicting the natural frequencies of sandwich composite panels under varying conditions. Nano‐filler reinforcement consistently increased natural frequencies across all vibration modes, regardless of boundary conditions. A parametric study revealed that natural frequency monotonically increased with higher aspect ratio and weight fraction of MWCNTs and Ti3C2Tx‐MXene. However, the thickness ratio had a significantly greater effect on natural frequency than other parameters. Clamping conditions also affected vibration behavior, with natural frequencies following the order: CFFF < SSSS < SFSF < CFCF < CSCS < CCCC. Regarding the transverse response, the root mean square velocity decreased with increasing MXene/CNT concentration and aspect ratio, attributed to enhanced stiffness and load‐bearing capacity of the hybrid sandwich composite. This study offers valuable insights for effective utilization of different types of nanoparticles in conjunction and design and development of nanoparticle‐reinforced sandwich composites, aiding in the prediction of the vibration behavior of these nanostructures.Highlights
