Huge amounts of unusable portion of leather and cattle hair from leather industries and chicken feather from poultries are polluting the environmental atmosphere tremendously. To reduce environmental pollution, these discarded parts need to use to produce other products. In this research, cow hair, chicken feather and waste leather were used to prepare useful composites combining with unsaturated polyester resin (UPR) to consider their reinforcement property and chemical property with view to curtail the environmental pollution. One portion of washed fibers was treated with aqueous solution of sodium hydroxide and the left portion was untreated. Then the chemically treated and untreated both portions of fibers were used to unsaturated polyester resin at 2, 5, 7, 10, 12 and 15 wt% fiber loading respectively. The composites were produced by hand lay-up technique and prepared composites were characterized by tensile and bending properties, Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM) and Thermo Gravimetric Analysis. Obtained all the results revealed best outcomes and significant enhancement in the properties of the composites with the optimum combination by 5 wt% treated cow hair fiber.
