Effect of Nanocomposite Structures on Fracture Behavior of Epoxy-Clay Nanocomposites Prepared by Different Dispersion Methods
Figure 11
Fracture surface micrographs (SEM) of nanocomposites made by ultrasonic dispersion of (a) 1 wt%, (b) 2 wt%, and (c) 3 wt% clay (high magnification pictures) and (d) 1 wt%, (e) 2 wt%, and (f) 3 wt% clay (low magnification pictures) in epoxy. The inserted schematic shows associated crack deflection mechanism.
