Abstract

This study examines the mechanical characteristics of a novel hybrid composite consisting of 25% ramie fiber, 15% kenaf fiber, and 2% titanium dioxide particles. Ramie fiber is known for its tensile rigidity and durability, while kenaf fiber is valued for its availability and biodegradability. Titanium dioxide particles are included to enhance the composite's mechanical properties. Mechanical tests—including tensile, bending, impact, and hardness—were conducted, revealing an average tensile strength of 66.14 MPa, a flexural strength of 86.46 MPa, an impact strength of 35.88 kJ/m², and a hardness of 181.8 HV. The significance of this study lies in its innovative combination of natural fibers with inorganic particles, addressing the demand for high-performing yet eco-friendly materials. The novelty of the composite is reflected in the strategic integration of ramie and kenaf fibers, which offer complementary mechanical properties, with titanium dioxide particles to enhance overall performance. This approach achieves a balance between strength, rigidity, and impact resistance while maintaining environmental sustainability. The inclusion of titanium dioxide boosts mechanical performance without compromising the material's eco-friendly nature. These findings suggest that this composite is suitable for technical applications requiring exceptional strength, rigidity, and impact resistance. This research contributes to the advancement of composite materials technology, showing potential for the development of sustainable and effective materials across various industries.
