Abstract: The thermo-mechanical behaviour of Aluminium alloy reinforced with nanoclay particulate was investigated by resonant-bar method. The aging response was detected in specimens, damping and DSC observation. The damping capacity of composite increased with increasing reinforcement of nanoclay and showed a peak in damping capacity during aging. These results indicate that the aging and precipitation kinetics in the matrix alloy are significantly accelerated due to the presence of reinforcement. The damping mechanisms, intrinsic damping, interface damping, dislocation damping and grain boundary damping are discussed.
