Mechanical Properties and Microstructure of Short Carbon Fiber Reinforced Hydroxyapatite Bio-composite
The short carbon fiber (Cf) reinforced hydroxyapatite (HA) bio-composite was prepared by an in-situ processing. Mechanical properties and microstructure of Cf/HA were investigated. Structures of HA was analyzed using XRD and fracture surface morphologies of bio-composite were analyzed using SEM. Result shows that grain size of HA under hot pressing sintering (1423K, 35MPa) grow up to approximately 50nm. Bio-composite exhibits excellent mechanical properties when Cf mass fraction is 3％, whose flexural strength and flexural modulus reach the maximum values of 130MPa and 36GPa which surpass common level of nature bone. SEM fracture surface morphologies of Cf/HA shows Cf can be uniformly dispersed in the HA matrix when the mass fraction less than 6％, while when the mass fraction is11％, partial aggregation appears.
