Here we prepared and characterized porous ceramic/polymer composites with high open porosity contents (>70%). We characterized the effect of different experimental conditions (infiltration cycles, polymer concentration, centrifugal speed) on the mechanical response. We showed that the nature of the polymer (brittle or ductile) may change the fracture behavior of ice-templated porous composites. PCL has a moderate impact only on properties linked to crack initiation (flexural strength, fracture toughness, strain), as already shown for dense ceramic/organic composites by Niebel et al. , but a strong impact on the crack propagation (strain energy release and strain to failure). In contrast, epoxy infiltration does not change the fracture behavior (brittle fracture) of porous composites although the flexural strength is slightly improved. No adhesion was found between the polymer and its ceramic substrate. Improving the adhesion by a chemical bounding (grafting) could certainly further improve the mechanical properties. These results are encouraging since the approach is applicable to other systems such as hydroxyapatite/PCL that could be used for synthetic bone substitutes. An increase of the energy stored for the material before total failure could increase the mechanical stability and facilitate their handling and transport, while maintaining an open porosity.
