orthopedic materials due to PEEK outstanding properties, which could overcome the disadvantages
of currently used metallic and ceramic materials. In the study HA/PEEK compositematerials were successfully
prepared via an in situ process, for the first time, in order to improve the mechanical performance of the
existing HA/PEEK composites. The structure of the lab-synthesized materials was characterized by infrared
spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM), and the mechanical
performance was investigated by a tensile strength test. The results exhibit the strong bonding between hydroxyapatite
fillers and PEEK matrix and good mechanical properties of the composites, suggesting that the
in situ synthesized HA/PEEK composite materials are promising for orthopedic applications.
