Micromechanical model for hydroxyapatite whisker reinforced polymer biocomposites
A micromechanical model was developed to predict the elastic moduli of hydroxyapatite (HA) whisker reinforced polymer biocomposites based upon the elastic properties of each phase and the reinforcement volume fraction, morphology, and preferred orientation. The effects of the HA whisker volume fraction, morphology, and orientation distribution were investigated by comparing model predictions wi...
متن کاملModeling the Anisotropic Mechanical Properties of Hydroxyapatite Whisker Reinforced Biocomposites
The ideal bone substitute biomaterial should have mechanical properties similar to that of human bone tissue. Hydroxyapatite (HA) alone suffers from low fracture toughness, and most polymers alone lack sufficient stiffness and strength, limiting applications in load-bearing implants. Synthetic HA whisker reinforced polymer biocomposites provide a means to overcome these deficiencies (Roeder, et...
متن کاملHydroxyapatite - starch nano biocomposites synthesis and characterization
Bone like hydroxyapatite (nHAp) was synthesized via an in situ biomimetic process in presence of wheat starch. The effect of polymer concentration alteration on the final structure of nHAp was investigated. Formation of the nHAp at room temperature was confirmed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Size and morphology of the nHAp samples were character...
متن کاملOsteoconductive Nanocomposite Coating of Apatite-Wollastonite and Chitosan
Here, we show the importance of the marine biomaterial chitin and its derivative, chitosan, in bioimplant applications. Titanium and titanium alloys have shown high potential for load bearing in bioimplant applications. However, after their application, a bond with living bone often does not develop or the integration of the implants with bone tissue takes several months. Moreover, the surface ...
