Fly ash is the mineral residue from the combustion of organic or inorganic materials, sourced from coal, biomass, volcanic activity, and industrial processes. Its composition and properties vary depending on the source and combustion conditions. Ash-filled thermoset-based composites are innovative materials created by incorporating ash into polymer matrices, enhancing mechanical properties and reducing costs while supporting environmental sustainability. These composites are widely used in industries such as construction, automotive, electronics, and packaging. In this study, fly ash obtained from hazelnut tree wood combustion was used as a filler in polyester resin, a commonly preferred material in composites. The composites were prepared by mixing specific proportions of ash with resin and hardened using the open casting method with Teflon molds. Mechanical properties were evaluated through tensile, Izod impact, hardness, and density tests, while microstructural analysis of fractured surfaces was performed via scanning electron microscopy. As a result of the study, it was evaluated that fly ash can be used as a filler in polyester-based composites. Such natural wastes are environmentally friendly, reduce waste management problems, and can provide added value by using them as fillers in composites.
