Summary

The concept of functionally graded material was originally developed in high technology industry, which was supposed to contain two contradictory properties including thermal conductivity and thermal barrier simultaneously. Nowadays, the reinforced metals with carbon nanotubes have become of much interest due to their desirable range of mechanical and thermal properties. In the study, described in this paper, the aim is to present a functionally graded material component which is composed of carbon nanotube reinforced aluminium composite-ceramic instead of pure aluminium. The reason of this material selection is that aluminium exhibits some unique characteristics such as low density, high thermal conductivity and considerable strength. In this paper, a functionally graded plate with aluminium matrix carbon nanotube-ceramic material is considered, which is subjected to thermal shock conditions. For the thermal conduction analysis and comparison of the temperature profile of pure metal-ceramic and metal matrix carbon nanotubeceramic, the differential quadrature method was utilized to solve the transient equations as a precise numerical method with a good convergence. It is found, nonuniform hyperbolic sine grid generations for discretising the time dimension is more suitable than uniform meshing. The results obtained are in good agreement with the previous work using the finite difference method, the finite element method and exact solutions.
