In the present era, recycling and reducing environmental pollution are the main objectives of sustainable development. Many researchers are thinking of innovation in the field of composite technology by utilizing waste material. The objective of this work is to check the effect of a human hair (waste material) as fiber on physical and mechanical properties. Tensile, flexural, impact strengths and hardness of human hair based polyester composite were evaluated to assess the possibility of using it as a new material in various engineering applications for longer life. The addition of polyester to the human hair fiber with marble dust adds as filler to increase the Impact strength of fabricated composite. Samples are fabricated by the hand lay-up process (40: 20: 40 matrix, filler and fiber ratio by weight), and the mechanical properties like tensile, flexural, impact using the Universal Testing Machine, Hardness test using Rockwell hardness testing machine, Impact using Izod impact test were all evaluated. It is an eco-friendly, long life and cost effective solution for various applications.
