The aim of this study is to compare the metallic and natural fiber reinforced polymer composite bone plates used in humerus fractures. A 3D finite element model was developed to analyze the performance of both types of plates. This study proposed on fabrication of natural fiber powdered material (like Sisal (Agave sisalana), Banana (Musa sapientum) and Roselle (Hibiscus sabdariffa)) Reinforced Polymer (NFRP) composite plate material with bio epoxy resin. Instead of orthopaedics alloys such as titanium, cobalt chrome, stainless steel and zirconium, this plate material can be used for both internal and external fixation on human body for fractured bone. In this study, flexural rigidity of Sisal and banana (hybrid), Roselle and banana (hybrid) and Roselle and sisal (hybrid) composite at dry and wet conditions was studied. In this study the composition of the microstructure of composites specimens were studied using Electron Dispersive X-Ray Thermo detector and Scanning Electron Microscope.
