This article investigates the dynamic characteristics of graphene nanoplatelet (GPL) reinforced rotating laminated composite cantilever plates using the element-free improved moving least-squares Ritz (IMLS-Ritz) method. The modified Halpin-Tsai model and rule of mixture are employed to predict the effective material properties. The energy functions of rotating GPL reinforced composite (GPLRC) cantilever plates are obtained by the first-order shear deformation theory (FSDT) including the rotational effects. Based on the IMLS-Ritz approximation, the discrete vibration equation of rotating GPLRC cantilever plates is derived. The accuracy of the IMLS-Ritz results is examined by comparing the natural frequencies with those obtained from published values. A comprehensive parametric study is carried out, with a particular focus on the effects of rotating speed, weight fraction, distribution pattern, total number of layers, and geometric parameters of rotating plates on the natural frequencies. Results show that a small amount of addition of GPLs can greatly increase the natural frequency of rotating GPLRC cantilever plates. The increment of natural frequency shrink when rotating speed is sufficiently high.
