Active vibration control of laminated carbon nanotube-based polymer composite plates using finite element analysis

Abstract

This study presents an investigation based on the active damping response of hybrid fiber-reinforced composite (HFRC) incorporated with straight and wavy carbon nanotubes (CNTs). In the novel HFRC, the carbon fiber and CNTs are homogeneously dispersed in the matrix phase. The CNT waves are assumed to be coplanar with two mutually orthogonal planes. A Mori−Tanaka (MT) model is established to estimate the elastic stiffness of the HFRC. The results of the MT model proposed that the elastic constants in the transverse direction are significantly enhanced due to the CNT waviness. A finite element (FE) model is derived by incorporating the layerwise first-order shear deformation theory (FSDT) to study the damping response of the HFRC smart plates embedded with the patches of active constrained layer damping treatment. Our investigation reveals that the damping characteristics of HFRC plates are significantly influenced by the waviness of CNT and the boundary conditions of the plate. © 2024 Elsevier Ltd.
