Experimental investigation on compression and bending properties of epoxy composites reinforced with Al2O3, kenaf/hemp fibers for orthopaedic implants

Abstract

Composites in medical sectors are effective and productive phenomena in fulfilling various necessary demands. Through proven results as a base, this technique can be used for further research to enhance the existing parameters. In this connection, present research extensively focuses upon studying the mechanical properties (Compression and Bending) and characterization of fibre reinforced composite materials along with Al2O3 as filler materials. Present study involves the investigation of mechanical properties like compression and bending for NFRPC (Natural Fiber Reinforced Polymer Composite) as bio material, Epoxy resin-LY556 as matrix material, using suitable hardener and natural fibers (Kenaf/Hemp) as reinforcement materials considering Al2O3 as filler material with appropriate percentage to enhance strength and hardness of the composites. Prepared specimens were subjected to (Compression/D-3410 and Bending/D-790) examinations. Later they were compared with the femur bone properties. It was noticed that NFRPC properties will match the femur Bone Strengths and results shows 12, 18 & 24% of NFRPC material are appropriate for orthopaedic implants. From the investigated results finally, it concludes that the mechanical properties like compression and bending will be increased with increasing proportion of fiber in composites.
