## 3 Results and Discussion
### Impact Simulation  
Figure 8 shows the impact energy absorption graph for jute fiber-reinforced epoxy composites with 90/0\({}^{\circ}\) orientation with different reinforcement volumetric fractions. The creation of a detailed 3D model of the Bajaj motorcycle fairing marked a key step in our engineering project. Using photogrammetry, high-resolution images captured the vehicle from various angles, enabling accurate reconstruction in SolidWorks. This model became a vital tool for visualization, analysis, and manufacturing, offering insights into the fairing's structural and aesthetic dynamics. The integration of digital technologies optimized development and ensured well-informed design decisions aligned with performance goals. \begin{table}

In motorcycle fairing design (see Figure 9), components like the tail section and fender improve aerodynamics, protect the rider from impacts and engine heat, and preserve critical parts of the vehicle [33]. Using epoxy composites reinforced with jute fibers enhances the fairing's mechanical properties, offering a sustainable alternative that improves impact resistance and durability. By adjusting the volume fraction of jute fibers, manufacturers can optimize these composites for better rider protection and vehicle performance [4]. Recent Computational Fluid Dynamics-CFD based studies on high-performance motorcycle fairings, such as those conducted on the Honda(tm) RS, confirm that even small aerodynamic refinements can yield measurable performance gains--emphasizing the importance of material optimization and design synergy [34]. The aerodynamic behavior of motorcycle fairings is not only governed by geometry but also by the physical properties of the material used. Studies with fiberglass prototypes have shown that lighter, smoother materials can significantly reduce drag forces and improve stability at high speeds--insights that support the exploration of natural fiber composites such as jute for sustainable and functional fairing designs [35]. The computerized impact simulation modeled the motorcycle front fairing using a jute fiber-reinforced epoxy composite. The results, obtained through a finite element analysis, provided critical metrics such as directional deformation and Von Mises equivalent stress. These indicators are essential for evaluating the fairing's structural response under impact loads. Directional deformation offers a detailed view of the fairing's distortion in the direction of impact, while the Von Mises equivalent stress is a key parameter for determining the onset of yielding or material failure under multiaxial loading conditions. Figure 8: Impact energy absorption results for jute fiber-reinforced epoxy composites. Von Mises Equivalent Stresses  
The finite element simulation conducted in ANSYS for the motorcycle front fairing, as shown in Figures 5 and 10, composed of an epoxy resin matrix reinforced with 26.7% jute fiber, indicates a maximum Von Mises equivalent stress of 35.12 MPa at the established simulation time. When comparing this maximum stress value with the material's yield strength, experimentally determined as 41.80 MPa, it is observed that the stress induced by the simulated impact remains below the yield threshold.
