| Abstract: | Fly ash reinforced polyetheretherketone (PEEK) composites were fabricated using compression molding technique. The fly ash surface was chemically modified using vinyltrimethoxy silane and 3‐aminopropyltriethoxy silane. The properties of treated fly ash PEEK composites were examined in terms of scanning electron microscopy, dynamic mechanical thermal analysis, differential scanning calorimetry, and thermo gravimetric analysis. The modified fly ash was observed to disperse more uniformly than the unmodified counterpart. The tensile strength and modulus also improved with treated fly ash filled PEEK composites. The increment of the dynamic modulus for the PEEK/treated fly ash composites is 32% at 250°C, indicating apparent improvement of high temperature mechanical properties. POLYM.
