Abstract

Composite materials, containing carbon nanotubes or vapor-growth carbon fibers, provide excellent thermal conductivity and specific intensity, and the thermal characteristics of the materials have been studied intensively in recent years. In the present report, a method of vibration analysis is proposed to obtain natural frequencies and mode shapes of circular plates composed of VGCF and aluminum layers. The Ritz method is used to derive a frequency equation. The finite element analysis is also made to calculate frequencies of the plates for comparison, and the accuracy of the Ritz solution is established.
