Fabrication and characterization of a composite material from polymer matrix using citrus limetta fiber

Natural fibers, known for their excellent mechanical properties, non-abrasiveness, affordability, high specific strength, environmental friendliness, and biodegradability, are increasingly being considered as potential replacements for synthetic fibers like glass and carbon. This study investigates the use of Citrus limetta peel fibers to develop and characterize a polymer matrix composite. The fibers were extracted, purified, and coated with epoxy resin, then developed into composites using the hand layup method and cured in an oven. Mechanical tests, including hardness, impact, tensile strength, and compression strength, were conducted to assess the composites. The results showed that fiber reinforcement significantly enhanced mechanical stability, with compression strength and ultimate tensile strength reaching 231.39 MPa and 22.68 MPa, respectively. Microstructural analysis using scanning electron microscopy (SEM) and moisture absorption tests were also performed. Additionally, Ansys workbench software was utilized for further analysis. The study concludes that Citrus limetta peel fibers are a viable reinforcement material for polymer matrix composites, offering enhanced mechanical properties. This research is relevant for applications in industries seeking sustainable and high-performance composite materials.
