Graphene Oxide reinforcement was suspended in a stabilized aqueous solution and applied, prior to each ARB&lt;br /&gt;
cycle, through airgun spraying. Different concentrations (graphene oxide/milipore water) were used and for&lt;br /&gt;
each concentration, samples produced have undergone up to 5 rolling cycles.&lt;br /&gt;
Optical and electron scanning microscopies were used for microstructural characterization which revealed a&lt;br /&gt;
non-homogenous deformation of the layers across the composite's thickness.&lt;br /&gt;
Although the presence of graphene-oxide promoted an increase in the microhardness, higher values were&lt;br /&gt;
obtained with its lowest concentration for similar samples. The number of ARB cycles and the direction of the&lt;br /&gt;
tested sections also influenced the microhardness results since the 5-cycle samples and the rolling direction&lt;br /&gt;
sections for all the samples achieved higher hardness results. Graphene Oxide revealed to be a major contributor&lt;br /&gt;
to the increase of stiffness during bending of the tested samples.&lt;/p&gt;
