  Abstract

This research investigates the mechanical and thermal properties of fiber-reinforced polyester composites incorporating silane-treated fibers and granite dust fillers. The fatigue, creep, thermal conductivity, and water absorption properties were evaluated to determine the influence of reinforcement and filler content on composite performance. Fatigue test results indicate that specimen PPG2, with 2 vol.% granite dust, exhibited the highest fatigue resistance, with load values of 24,711 N, 21,711 N, and 18,741 N at 25%, 50%, and 75% of UTS, respectively. This improvement is attributed to the optimal combination of fiber reinforcement and filler content, ensuring effective stress distribution and superior fiber-matrix bonding. In contrast, specimen PPG3, with 4 vol.% granite dust, demonstrated the best performance in creep resistance, thermal insulation, and water absorption properties. The creep strain values for PPG3 were recorded as 0.0059, 0.0068, and 0.0084 at 5000, 10,000, and 15,000 s, respectively, indicating superior resistance to time-dependent deformation due to increased filler content acting as rigid barriers within the matrix. Additionally, PPG3 exhibited the lowest thermal conductivity of 0.24 W/mK, highlighting its excellent insulating properties, as the presence of higher filler content disrupted heat transfer pathways. Water absorption values for PPG3 reached 0.042%, the highest among the tested specimens, which is associated with the hydrophilic nature of granite dust particles at higher filler concentrations. The scanning electron microscope (SEM) analysis further confirmed the structural integrity of the composites, with PPG2 displaying well-dispersed fillers and strong adhesion at the fiber-matrix interface, while PPG3 exhibited slight delamination due to increased filler content. These findings underscore the importance of optimizing reinforcement and filler content to enhance the fatigue and thermal properties of polyester composites for structural and industrial applications.
