Vibration analysis of hybrid composite plates reinforced with one ply of single-walled carbon nanotubes

Abstract

due to their spectacular properties, carbon nanotubes (CNTs) will open a wide horizon and a new field of creativity, research and innovation in many high performance applications. Inspired by this feedback and to improve the mechanical characteristics of a laminatesd composite plate based on unidirectional fibers without adding additional weight, one of the plys constituting the laminates has been replaced by a ply in CNT single-layer in this approach, the chosen displacement field is based on the theory of Yang, Norris and Stavsky. as well a computer program using the finite element method for calculating natural frequency has been developed. Two parametric studies were carried out: one on the influence of the interchangeability of the ply in CNT and the other on the effect of the angle of orientation of fibers in CNT. A good correlation was observed by comparing the results obtained with those available in the literature.
