Abstract

In order to better understand the micromechanical behavior of carbon nanotube filled polymers, the load transfer behavior and interfacial shear stress must be quantified. This paper presents preliminary work on an experimental technique for quantifying the relative interfacial shear stress in multi-walled carbon nanotube / polycarbonate composites. The procedure provides a comparison of the aspect ratio of the nanotubes pulled from a fracture surface. In addition, the correlation with pullout angle is discussed. This work showed a decrease in the aspect ratio and thus an increase in interfacial shear as a result of chemical surface modification to multiwall nanotubes.
