The present work reports the synthesis, fabrication and characterization of hydroxyapatite (HAp) based polyethylene bio-composites as an artificial bone implant material. The main problem with the metallic bone implants is the stress shielding and bone regeneration, which may be overcome by introducing polymer based light weight bone implants. HAp was synthesized by wet chemical precipitation technique and mixed with high density polyethylene (HDPE) and high molecular high density polyethylene (HMHDPE) using micro-compounder and twin screw extruder. Mocro-injection molding and compression...
