INVESTIGATION OF MECHANICAL PROPERTIES OF POLYESTER REINFORCED WITH HEMP FIBRE (LONG FIBRES AND MAT) FOR PATELLAR IMPLANT APPLICATION

This paper includes the study of basic mechanical properties of polymer composites prepared for polyester as matrix and natural fibers (Hemp long fiber and Hemp mat fiber) as reinforced materials with different compositions of 10%, 20% and 30% reinforcement used for patellar implant material. Over the past centuries, there is lot of research works carried out in the medical field and materials science in development of biomaterials for implant applications. So, many different materials are used as implants for replacing of damaged parts. Over the years, SS316L and UHMWPE have established as the best available patellar implant materials. In advancing field of material science, metallurgy and designing, still there is scope for development for more advanced bio-materials with better properties. It has been observed that the mechanical properties of Polyester reinforced with Hemp fibre (long fibres and mat) show better properties than UHMWPE. These properties of composites are found to be suitable for the patellar implant material.
