Abstract :
Natural fiber-reinforced epoxy composites have become a subject of significant research due to their eco-
friendly nature, lightweight properties, and competitive mechanical performance compared to traditional synthetic
composites. This study focuses on the mechanical behavior and tensile strength characteristics of natural fiber-reinforced
epoxy composites and correlates them with microstructural, thermal, and chemical analyses. The investigation emphasizes
the use of advanced techniques such as scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and
Fourier-transform infrared spectroscopy (FTIR) to understand the fiber–matrix interface, thermal stability, and chemical
bonding mechanisms. The results show that appropriate fiber surface treatments and optimized fiber loading enhance the
tensile strength and interfacial adhesion between the natural fibers and epoxy matrix. The analysis further reveals that the
improved thermal resistance and chemical compatibility contribute to the composite’s superior performance in
engineering applications. This comprehensive characterization provides a framework for designing high-strength,
sustainable composite materials for structural, automotive, and aerospace applications.
