Integration and mechanical and water absorption characteristics of treated natural fiber-titanium nanoparticles embedded polyester composites
This research investigates the integration and functional properties of polyester composites reinforced with treated natural neem fiber and varying concentrations of titanium nanoparticles (Ti). Fabricated via hot compression moulding, the composites show enhanced tensile strength (89.6 MPa), impact toughness (4.3 J/mm²), microhardness (34 HV), and reduced water absorption (1.5% at 14 days) with optimal Ti nanoparticle loading. The AB4 composite (16 wt% neem fiber, 6 wt% Ti nanoparticles) demonstrates superior performance, making it suitable for automotive cabinet and seat frame applications. The study emphasizes the effective dispersion and strong interfacial bonding achieved, which contribute to improved mechanical and thermal stability.

The AB4 composite (polyester/16 wt% neem fiber/6 wt% Ti nanoparticles) exhibited the highest tensile stress of 89.6 MPa, a significant improvement over the base polyester (71 MPa) and neem fiber-only composite (73.5 MPa). This enhancement is attributed to the strong interfacial bonding between the treated neem fibers, uniformly dispersed Ti nanoparticles, and the polyester matrix, which effectively transfers stress and restricts crack propagation under high loads. The presence of nanofillers strengthens the structure and allows it to endure maximum loads.

The AB4 composite (16 wt% neem fiber, 6 wt% Ti nanoparticles) showed the lowest moisture absorption among the reinforced composites, with 1.5% at 14 days. This reduced absorption is due to the chemical surface treatment of neem fibers, which minimizes capillary action, and the ability of Ti nanoparticles to occupy microvoids and block water diffusion pathways, enhancing the surface hydrophobicity of the composite.

Water Absorption Reduction (AB4 vs AB1)
The AB4 composite demonstrated a 20% improvement in resisting water capillary action compared to the AB1 composite (Polyester/16 wt% treated fiber), attributed to Ti nanoparticles.
| Composite Sample | Water Absorption (7 days) | Water Absorption (14 days) |
|---|---|---|
| AB (Polyester) | 0.32% | 0.32% |
| AB1 (Polyester/Neem) | 1.9% | 1.8% |
| AB4 (Polyester/Neem/Ti) | 1.5% | 1.5% (lower than AB1) |
| Conclusion: The addition of Ti nanoparticles significantly reduces water absorption in polyester/neem fiber composites, demonstrating improved resistance to moisture. | ||
The composites with 16 wt% neem fiber and varying Ti nanoparticles showed better thermal stability compared to the base polyester. The AB4 sample (16 wt% neem fiber, 6 wt% Ti nanoparticles) exhibited a T95% of 245°C, an 11% improvement over the polyester matrix (215°C). The synergistic effect of neem fiber and Ti nanoparticles, occupying a larger surface area, helps endure maximum temperatures and limits composite weight loss during thermal degradation.

Thermal Stability Improvement (AB4 vs Base)
The AB4 composite shows an 11% better thermal stability (T95% at 245°C) than the polyester matrix (T95% at 215°C).
Automotive Sector Application
The enhanced properties of the AB4 composite, including its superior thermal stability, make it an ideal candidate for automotive cabinet and seat frame applications. Its ability to withstand higher temperatures, combined with improved mechanical strength, contributes to safer and more durable components in demanding automotive environments. This material offers a significant advantage in reducing material degradation and extending product lifespan.
