Fractography analysis of 0.5 wt% multi-layer graphene/nanoclayreinforced epoxy nanocomposites
The topographical features of fractured tensile, flexural, K<sub>1C</sub>, and impact specimens of0.5 wt% multi-layer graphene (MLG)/nanoclay-epoxy (EP) nanocomposites have been investigated.The topographical features studied include maximum roughness height (R<sub>max</sub>...
