Özet
In this study, polyester and vinyl ester resins were used as matrix materials, while pine root, cotton waste, and corn stalk waste were selected as reinforcement materials. The effects of combining these wastes at different reinforcement ratios on the thermal and mechanical performance of the composite samples were investigated. Composite test specimens were produced using the open molding method with agricultural waste reinforcement at 2.5%, 5%, and 10% by weight. Hardness and tensile tests were applied to determine the mechanical properties of the obtained specimens, while thermal conductivity measurements were performed to determine their thermal behavior. The findings showed that the vinyl ester matrix composite specimen with 2.5% corn stalk waste filling exhibited the highest tensile strength, while the polyester matrix composite specimen with 10% cotton stalk waste filling showed the lowest strength. Similarly, the polyester matrix composite specimen with 2.5% cotton stalk waste filling had the highest hardness value in the hardness tests, while the polyester matrix composite specimen with 10% pine root waste filling had the lowest value. In thermal conductivity tests, the highest thermal conductivity value was measured in the vinyl ester matrix composite sample filled with 2.5% corn waste, while the lowest value was measured in the polyester matrix composite sample filled with 2.5% pine root waste. In conclusion, it has been shown that environmentally friendly and sustainable composite materials can be obtained by integrating agricultural wastes into polymer matrix composites, and that this will provide an innovative and alternative contribution to fields such as automotive, insulation, and construction applications.
