Composites are compiled at least by two different materials, each acting as a matrix and reinsforce (amplifier). In this research hydroxyapatite plays as a matrix whereas chitosan as reinforce. In this study, the composite HAp-chitosan is synthesized using Geloina coanxans as a source of kalisium using two types of solvent water and HNO3, (NH4)2HPO4 as a source of Fospat and is composited with …
