Abstract

In this review paper, the dynamic characterization and structural optimization of a carbon nanotube reinforced laminated hybrid composite plate are surveyed. The governing differential equations of motion of a carbon nanotube (CNT) reinforced hybrid composite plate based on higher-order shear deformation theory is reviewed in finite element formulation. The stiffness and damping properties of the composite plate are significantly varied depending upon the percentage of CNT reinforcement and aspect ratio of CNT. The validity of the developed formulation is demonstrated by comparing the natural frequencies evaluated using present FEM with those of experimental work and available literature. Various parametric studies are also performed to investigate the effect of aspect ratio and percentage of CNT content and ply orientation and boundary conditions on carbon nanotube and mode shapes of a carbon nanotube-reinforced composite plate. The optimal ply configuration, aspect ratio and volume fraction of CNT can be identified by formulating the multi-objective optimization problem to yield the maximum stiffness and modal damping factors. The significance of CNT reinforcement and simulated results may serve as guidelines in designing laminated hybrid composite plate structures used in aerospace. This study will provide a useful reference to the design and fabrication of fiber-reinforced plastics for many instruments such as automotive components, golf shaft for sports, bicycle helmet for sports, the body of the sailing vessel, wind turbines, spacecraft, space elevators, solar panels and so on.
