Abstract：Natural materials such as human teeth and bones have remarkable mechanical properties. However, nature grows these biological materials from a bottom-up approach using a biologically controlled self-assembly process. In this talk, I will discuss a top-down approach from a powder processing route for the fabrication of hierarchically structured ceramic/polymer or metal/polymer composites to offer cost-effective engineering solutions for potential applications in orthopaedics and dentistry. Freeze casting technique was used to create such hierarchical structures in metals (e.g. Ti) and ceramics (e.g. alumina). Biomimetic composites were produced with infiltration of polymers or hydrogels. The composites possess anisotropic, graded and interpenetrating multi-phase microstructures with performance surpassing conventional monolithic and isotropic materials currently used in clinic.
