Natural Vibration Analysis of Hard Coated Carbon Fiber Reinforced Composite Plates
Based on the finite element principle of anisotropic materials,a finite element model of hard coating-carbon fiber reinforced composite plates was established.Considering the influence of hard coat-ing,the modal analysis was carried out on the structure to obtain the natural frequency,and the influence of hard coating on the inherent characteristics of the structure was analyzed,which provides a basis for the application of hard coating material on the carbon fiber reinforced composite blade.The results show that piezoelectric coating can reduce the natural frequency of carbon fiber reinforced composite plates,and the piezomagnetic coating can increase the natural frequency,and the influence of piezoelectric coating on the intrinsic characteristics of the laminates is greater than that of piezomagnetic coating.
