Characterization and Optimization of Hybrid Epoxy Composites Using Chicken Feather Fibers and TiO₂ for Enhanced Tensile Strength

Abstract

Introduction: Hybrid epoxy composites reinforced with chicken feather fibers (CFF) and titanium dioxide (TiO₂) are promising candidates for advanced structural applications due to their lightweight nature and enhanced mechanical properties.

Objective: In this study, the tensile strength of these hybrid composites was optimized using the Taguchi technique. An L27 orthogonal array was employed to systematically evaluate the influence of three critical factors: composite composition, filler type, and filler percentage on the tensile load.

Methods: The Taguchi method facilitated the identification of the optimal process parameters, providing a robust framework for understanding the interactions among the variables.

Results: Experimental results demonstrated that composites incorporating CFF exhibited superior tensile performance compared to those reinforced with TiO₂. Analysis of signal-to-noise ratios revealed that both the composite composition and filler type significantly affect tensile strength, with a notable optimum observed for a specific configuration where a 4% concentration of CFF yielded the highest tensile load.

Conclusion: This study not only highlights the potential of using chicken feather fibers as an eco-friendly and cost-effective reinforcement in epoxy composites but also underscores the efficacy of the Taguchi technique in material optimization. The findings offer valuable insights for the development of high-performance hybrid composites with enhanced tensile properties for diverse engineering applications.
