Hydroxyapatite (HA) has limitations in fracture toughness and flexural strength, hindering its use as an implant material in biomedicine.
The study improved HA composites by incorporating boron nitride nanoplatelets (BNNP) and using spark plasma sintering, resulting in finer grain structure and enhanced mechanical properties.
Although the Weibull Distribution indicated reduced mechanical reliability, the BNNP-reinforced composites maintained a low probability of failure and a safety factor comparable to human bones.
