This study investigates the impact of composite materials consisting of Polycaprolactone (PCL), Magnesium (Mg), and Hydroxyapatite (HA) on the strength and degradation ability of synthetic bone grafts. These materials are mixed in various proportions, namely 90% PCL, 70% PCL 50% PCL, using chloroform as a solvent. The primary aim is to produce artificial bone grafts that closely mimic the chara…
