Due to the superior performance of plastic composites, they are widely used in various engineering applications. Additionally various fillers are added to the composite materials in order to improve their properties and to reduce raw material costs. In this study, fly ashes with different compositions obtained from two thermal power plants, Afşin and Soma, were used as filler material. As control group, plain woven E-glass fabric reinforced polyester composites and as experimental groups Eglass/polyester composites filled with fly ashes at various amounts (5, 10, 20 and 30 wt%) were produced. Samples were cut with tile saw according to related ISO standards. Mechanical performance of both control and experimental groups were characterized with tensile test, bending test, impact test and hardness besides surface roughness. Also the fractured surfaces were observed by Scanning Electron Microscope. According to the results it was observed that, with the addition of fly ash, tensile, bending and impact strength values decreased where hardness increased significantly.
