Bioinspired ceramic-polymer composites with multilayered architecture have drawn significant attention because of the possible synergy of strength and damage-tolerance. Ice-templating is a unidirectional solidification process in which phase separation of solvent crystals and ceramic particles followed by freeze drying and sintering result in ceramic foams with directional porosity. Due to low pore tortuosity, polymer infiltration of ice-templated ceramic foams has emerged as a promising and versatile technique to develop this class of novel composites. It is expected that for compressive loading orientation parallel to ceramic and polymer layers, material response will be influenced by the ceramic phase. Whereas, for compressive loading orientation perpendicular to the layers, polymer phase will have significant influence. In this presentation, we will discuss about the effects of composition (ceramic to polymer ratio), morphology of ice-templated sintered ceramic phase, and loading orientation on uniaxial compressive response to shed light on the structure-property relationships.
