Abstract: The aim of this experimental study was to investigate the mechanical properties of epoxy polymer matrix composites reinforced with Synthetic fiber (S-glass) and ceramic filler, specifically Silicon Carbide (SiC), under different filler loading conditions. The combination of SiC as a secondary reinforcement with S-glass fiber was fabricated using the hand layup technique, incorporating filler loadings of 0%, 2.5%, 5%, and 7.5% by weight. Tensile testing was performed on samples prepared and cut according to ASTM standards at various temperature conditions. The results of the tests revealed that the addition of 7.5% SiC filler into the S-glass fiber reinforced epoxy composite significantly enhanced the tensile properties of the material, surpassing those of other composites under both normal and high temperature conditions. These findings suggest that as the SiC ceramic filler content increased in the composite, the mechanical properties exhibited proportional improvement, irrespective of the temperature conditions. This experimental research provides valuable insights into the characterization of mechanical properties in epoxy polymer matrix composites reinforced with Synthetic fiber (S-glass) and Silicon Carbide (SiC) ceramic filler. The study highlights the importance of filler loading in optimizing the performance of these composites, specifically in terms of tensile strength, across different temperature environments.
