Abstract
This research focuses on optimizing the mechanical and thermal properties of hybrid fiber and particle-reinforced composites through systematic parameter optimization using the Taguchi method and Grey Relational Analysis (GRA). Composites were fabricated using varying fiber volume fractions (20%, 30%, and 40%), particle sizes (20 μm, 60 μm, and 100 μm), and curing temperatures (60°C, 80°C, and 100°C) in a 3-factor, 3-level experimental design. Key properties such as tensile strength, impact resistance, and thermal stability were evaluated, with optimization guided by signal-to-noise (S/N) ratios and GRA. The optimal combination was identified as 30% fiber volume fraction, 60 μm particle size, and 100°C curing temperature, achieving superior performance metrics: tensile strength of 290 MPa, impact resistance of 55 J/m, and thermal stability of 340°C.Compared to suboptimal settings, the optimized parameters led to a 15-20% enhancement in tensile strength, a 22% increase in impact resistance, and a significant boost in thermal stability, attributed to improved fiber-matrix bonding, uniform particle dispersion, and effective cross-linking during curing. The study demonstrated that higher fiber content improved reinforcement but required balance to avoid brittleness, while intermediate particle sizes ensured stress distribution without agglomeration. The curing temperature was pivotal, with 100°C achieving maximum cross-linking without risking thermal degradation. This work underscores the effectiveness of combining experimental design and GRA in tailoring composites for advanced engineering applications, offering a replicable framework for future optimization studies.
Keywords: Fiber reinforced composites, parameter optimization, mechanical properties, grey relational analysis, thermal stability.
