Award Summary
This technology aims to improve carbon neutrality through the effective use of carbon fiber reinforced polymers (CFRPs).
The technology creates 3D monolithic CFRP-aluminum structures by integrating anisotropic topology optimization, Turing pattern fiber path generation, tailored fiber placement and nano uneven anodization bonding, to optimize fiber function and material utilization.
A semi-monocoque prototype demonstrates the potential for 15% weight reduction compared to the reference design(45kg) in large 3D structures with complex topology using large fiber tow (50K) placed on 5 km of design paths with only 4% fiber waste. This experiment utilized our TFP method and TCWM, a composite fiber sewing machine.
Key benefits:
- Full-Lifecycle Carbon Neutrality
- Weight Reduction
- Minimized Fiber Waste and Assembly Cost
- Optimized Material Usage
- Advanced Manufacturing Process
About TFP process
Tailored Fiber Placement (TFP) is a technology to create preforms by placing fiber bundles with a computer-controlled embroidery machine. The conventional way, CFRP molding process using laminated carbon cloth has performance issues in shapes such as hollowed-out, doughnut, and
radial shapes due to the strong anisotropy of carbon fiber, which generates high strength and stiffness only in the fiber direction. It is also problematic in terms of material scrap rates.
In contrast, TFP process sews carbon fiber onto a substratebase material to form a preform. The continuous and free arrangement of fibers enables composite structural design that provides the required strength and stiffness in the required direction. In addition, the fiber can be minimally oriented without cutting, thus minimizing the scrap rate of the material. In short, TFP process could maximize the properties of carbon fiber to create even lightweight and high rigidity.
