Applications of natural fiber composites for replacement of orthopaedic alloys

In this research, powder material of natural fibers like Sisal (Agave sisalana), Banana {Musa sepientum) and Roselle (Hibiscus sabdariffa), Sisal and banana (hybrid) , Roselle and banana (hybrid) and Roselle and sisal (hybrid) are fabricated with bio epoxy resin using molding method. In this paper the optimum mixing of fiber and resin is achieved by using Taguchi method. In this work, flexural rigidity and hardness of Sisal and banana (hybrid), Roselle and banana (hybrid) and Roselle and sisal (hybrid) composite at dry and wet conditions were studied. In this, present work focuses on the prediction of deflection of the Natural Fiber Reinforced Polymer (NFRP) composite and the values compared with the mathematical model of deflection of beams and ANSYS solution and found to be in good agreement. In this work micro structure is scanned by the Scanning Electron Microscope. The objective of this research was an effort to utilize the advantages offered by renewable resources for the development of biocomposite materials based on biopolymers and natural fibers and in future this plate material externally coated by calcium phosphate and hydroxy apatite (hybrid) composite and it can be used for internal fixation and also external fixation on human body for fractured bone.
