Keratin-based polyester composites represent a promising class of materials combining the sustainability of natural fibers with the versatility of synthetic polymers. This study evaluates the abrasion resistance and mechanical properties of composites made from keratin and polyester to assess their potential for various applications, including durable textiles and structural components. Keratin fibers were extracted and incorporated into a polyester matrix to form composite samples. These samples underwent a series of tests to determine their mechanical properties, including tensile strength, elongation at break, and modulus. Additionally, abrasion resistance was assessed using standard wear tests to evaluate the composites' durability under conditions of friction and wear. The results indicate that the incorporation of keratin fibers significantly enhances the mechanical properties of polyester composites. Notably, the tensile strength and modulus of the composites increased with the keratin content, demonstrating improved load-bearing capacity. However, the elongation at break exhibited a trade-off, with higher keratin content leading to reduced flexibility. The abrasion resistance tests revealed that keratin-based composites exhibit superior resistance to wear compared to pure polyester, highlighting their potential for applications requiring enhanced durability.
