Mechanical behaviour of nanocomposites

Although the mechanical properties of carbon nanotubes (CNTs) have been studied extensively, the long term behaviour of CNTs or composites reinforced by this material is often left out. In this project, the creep behaviour of single-walled carbon nanotubes (SWNTs) embedded in PVB matrix was investig...
