Bioinspired approaches to toughen calcium phosphate-based ceramics for bone repair.

To respond to the increasing need for bone repair strategies, various types of biomaterials have been developed. Among those, calcium phosphate (CaP) ceramics are promising since they possess a chemical composition similar to that of bones. To be suitable for implants, CaP ceramics need to fulfill a number of biological and mechanical requirements. Fatigue resistance and toughness are two key mechanical properties that are still challenging to...
