Abstract

In recent years, the use of polymer composites derived from organic resources has significantly increased across various industries. This shift is largely driven by environmental concerns and the health risks associated with the production and disposal of traditional synthetic fibers. Natural fibers have gained popularity as reinforcement materials in polymer matrix composites due to their numerous advantages, including low cost, widespread availability, low density, favorable mechanical properties, environmental friendliness, high stiffness, and biodegradability.

In the present study, OBF (organic-based fibers) were treated with a 5% sodium hydroxide solution and then incorporated into epoxy resin (ER) as the matrix material. Composites were fabricated using varying OBF weight fractions of 3%, 6%, 9%, 12%, and 15% as filler material. The preparation and testing of the composites followed ASTM standards. To evaluate the physical and mechanical performance of the composites, tests were conducted for water absorption, tensile strength, hardness, impact resistance, and flexural strength.
