Notes:
Hydroxyapatite-based materials have been used for dental and biomedical applications.Newly developed synthesis techniques give cause to a broad field in the study of these materials andindustry demands products with better properties day by day. The purpose of the present work wasto evaluate the mechanical properties of hydroxyapatite-based (HAp-based), organic-inorganiccomposites.HAp-based, organic-inorganic composites were obtained by modified gel casting process andorganic molecules in a gelatin solution.HAp samples of different sizes and shapes were obtained with controlled micro and macro porosityand then were immersed into several gelatin solutions with different concentrations.X-ray powder Diffraction (XRD), Infra Red (IR) Spectroscopy and Scanning Electron Microscopy(SEM) techniques were used to analyze samples before and after gel casting process in order toassure that chemical and physical properties remains the same after this process. IR Spectroscopyand SEM techniques were used to characterize samples after the introduction of organic phase inorder to analyze the final morphology of samples. Mechanical characterization was made incompression mode to samples without and with different concentrations of organic phase in order toestablish the optimum conditions in which the highest compressive strength and Young’s modulusis reached
