The most common approach to improve the mechanical properties of porous ceramics is the incorporation of a ductile organic phase , to partially or completely fill the porosity. It is nevertheless crucial to have a continuous ceramic scaffold first to provide strength and rigidity to the material. A coated ceramic scaffold is thus stronger and more rigid than a porous blend of materials where ceramic particles are distributed in the polymer phase. The ceramic scaffold provides high stiffness and stress resistance while the polymeric phase provides a higher flaw tolerance. One simple way to obtain such materials is to infiltrate a sintered or partially sintered ceramic with an organic phase. Because of their interest for biomedical applications, most studies have focused on biodegradable synthetic polymers as polycaprolactone (PCL) , polylactideco-glycolide (PLGA) or poly (D-L-lactic acid)(PDLLA) . In all these studies, however, the initial porous structure was isotropic, with no preferential orientation of the macropores.
