The purpose of this work is to show the correlation between the fractal dimension, D, and mechanical properties such as work of fracture, γ wof , and fracture toughness, K Ic. Alumina-mullite-zirconia composites were characterized by the slit-island method, SIM, to obtain values of D and its fractional part, D*. The fracture surface roughness was also evaluated using a cyclic voltametric method. It will be shown that there is a positive experimental dependency of γ wof on D* and that there is not an evident correlation between K Ic and D*.
