carbon nano-tube (cnt) reinforced metal matrix nano-composites have attracted a great deal of attention in recent years due to the outstanding physical and mechanical properties of cnts. however, utilizing cnt as reinforcement for alloy matrixes has not been studies systematically and is still a challenging issue. in the present study, cu80fe20/10cnt nanocomposite was synthesized by mechanical ...

In this study, discrepancies between the free vibration of fiber-metal laminate (FML) and composite cylindrical shells reinforced by carbon nanotubes (CNTs) based on Love’s first approximation shell theory have been considered by beam modal function model. The representative volume elements consist of three and four phases for composite and FML structures, respectively, which include fiber, CNT...

An experimental method to follow the evolution of the precipitation phenomena in the metal-matrix composites using the thermoelectric power measurements is described. It is shown that one can follow the kinetics of the precipitation during aging. The influence of the reinforcement on the precipitation kinetics is studied in case of an aluminum 6061- SiC, composite (where SiC, represents SiC par...
