Flexural strength and fracture toughness of 53 wt% nano‐3Y‐TZP/PEKK composites (nano‐3Y‐TZP/PEKK) and functionalized cortical bone‐inspired composites (FCBIC). a) The three‐point bending test condition. b) The flexural strength of nano‐3Y‐TZP/PEKK and FCBIC compared to cortical bone (n = 3). c) Scanning electron microscope (SEM) image of UV‐notches on FCBIC. SEM image of crack propagation in d) cortical bone and e) FCBIC. f) X‐ray tomography (XRT) renderings of crack propagation in FCBIC. g) J‐integral, and h) K‐based fracture toughness with crack extension (n = 3). i) Young's modulus and brittleness index for FCBIC, compared with implant materials.
