Introduction to Weight Reduction in Solar-Powered Vehicles

In the realm of high-performance vehicles, especially solar-powered cars, the quest for efficiency is paramount, with weight reduction playing a pivotal role. The wheel, a crucial component, significantly influences a vehicle's range, handling, and acceleration. This blog delves into the development of a groundbreaking hybrid composite wheel designed for the Sunswift 7 solar car. By marrying automated fibre placement (AFP) with traditional hand layup techniques, this project not only addresses the challenges inherent in traditional wheel manufacturing but also paves the way for a new era of lightweight, durable vehicle components. Through meticulous design, rigorous analysis, and innovative manufacturing, a wheel that stands at the intersection of technology and sustainability was born, setting a new standard for the automotive industry.


The Limitations of Traditional Wheel Manufacturing

Traditional wheel manufacturing methods face significant challenges in meeting the advanced needs of solar-powered vehicles, particularly in achieving the optimal balance between lightweight construction and the requisite strength. Conventional processes often fall short in several key areas:

  • Material Utilization: Traditional methods may not efficiently use materials, resulting in wheels that carry unnecessary weight without proportionate gains in strength or durability.

  • Precision and Customization: Achieving the precise control over material placement and orientation necessary for optimal performance characteristics is difficult. This lack of precision can lead to suboptimal strength-to-weight ratios.

  • Innovation and Adaptability: Conventional wheel manufacturing is less adaptable to incorporating new materials or techniques that can significantly enhance performance by reducing weight while maintaining or improving strength.

  • Cost and Environmental Impact: Often, these methods are not only more resource-intensive but also less environmentally friendly, with higher waste levels compared to more modern, automated methods.


By contrast, the development of the hybrid composite wheel for the Sunswift 7 solar car, utilizing automated fibre placement (AFP) and hand layup, addresses these limitations head-on. This innovative approach allows for precise material placement, optimization of the strength-to-weight ratio, and reduced environmental impact, setting a new standard for wheel manufacturing in high-performance vehicles.


Innovative Manufacturing Approach for Wheel Design

The development of a hybrid composite wheel for the Sunswift 7 solar car represents a significant leap forward in wheel manufacturing technology. This process combines the precision of Automated Fibre Placement (AFP) with the versatility of hand layup techniques, embodying a synergistic approach to crafting wheels that are both lightweight and strong. Here’s how this innovative process unfolds:

Automated Fibre Placement (AFP)

This method is pivotal for creating the wheel disc, enabling selective reinforcement through strategically placed spokes. AFP allows for precise control over fibre orientation and placement, optimizing the structural integrity and minimizing material waste. The use of Path planning software ensures that fibre paths are optimized, significantly reducing overlaps and enhancing performance.

Hand Layup

For areas requiring intricate shaping and placement, such as the rim and tyre mounting region, hand layup proves invaluable. This technique provides the flexibility needed to address complex geometrical challenges, ensuring that every component of the wheel conforms to the highest standards of strength and weight efficiency.

Design and Analysis

Utilizing the ANSYS ACP PrepPost suite, the wheel undergoes rigorous numerical analysis to ensure that the design is not only optimized for weight but also meets the stringent strength requirements necessary for high-performance applications. This stage involves detailed simulations to predict and enhance the wheel's response to real-world loading conditions.



Optimization and Testing

Through a combination of theoretical analysis and empirical testing, the wheel design is refined to achieve an ideal balance between weight and durability. The final product undergoes mechanical testing to verify its performance, with results closely aligning with the predicted outcomes.


Development and Validation of the Hybrid Composite Wheel

The culmination of this project is the successful creation of a hybrid composite wheel for the Sunswift 7 solar car, a testament to the ingenuity and efficacy of combining automated fibre placement (AFP) with hand layup techniques. This section delves into the critical phases of manufacturing, integration, and validation:

  • Manufacturing Details: The wheel disc, fabricated using AFP, incorporates selective reinforcement in the form of spokes, optimizing the material's structural benefits while minimizing weight. The rim and tire mounting region are crafted through hand layup, ensuring intricate details are meticulously addressed.

  • Integration of AFP with Hand Layup: The seamless integration of these two manufacturing techniques allows for the wheel's components to be adhesively bonded, resulting in a wheel that exemplifies both lightweight characteristics and durability. This hybrid approach demonstrates the potential of combining traditional craftsmanship with cutting-edge automation.

  • Testing and Inspection Processes: The wheel underwent rigorous testing, including mechanical tests to assess its performance under load. The results were within 3% of theoretical predictions, validating the effectiveness of the design and manufacturing process. Furthermore, inspection techniques, including microscopy, were employed to ensure the integrity and quality of the composite materials.
