Here, we followed a similar approach with a stronger ceramic (yttria-stabilized zirconia) and investigated the mechanical properties of highly porous ceramicpolymer composites with unidirectional porosity. We developed a route to process such composites by partially infiltrating ice-templated scaffolds with a dilute polymer solution. We characterized the impact of polymer infiltration on microstructure and mechanical properties (flexural strength, work of fracture, toughness), and assessed the effect of two polymers with different mechanical behaviors: brittle (Epoxy) or ductile (PCL). We characterized the damage mechanisms by bending some of our notched samples in situ in a laboratory tomograph.
