Description : A full-scale variable axial carbon-fiber-reinforced plastic (CFRP) aluminum semi-monocoque was designed, fabricated, and evaluated. The prototype delivered a 15% weight reduction with minimal fiber waste (4%) and low assembly cost. This technology aims to improve carbon neutrality through the effective use of 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 weight reduction in large 3D structures with complex topology using large fiber tow (50K) placed on 5 km of design paths with only 4% fiber waste.

Description : The partners have engineered what’s described as the world’s first ultra-lightweight carbon-fiber-reinforced-thermoplastic composite vehicle door that is 45% lighter than steel while meeting static and dynamic crash performance metrics. The door is 100% re-processable, signifying a major advance in sustainable automotive design.
The innovation uses re-processable polyamide-based carbon-fiber laminates, which enable easy integration with existing sheet metal forming equipment. The approach includes systems engineering, leveraging finite element analysis for structural optimization, and reducing part count by 52% versus baseline doors. The partners developed a novel manufacturing-to-response pathway, incorporating extensive material testing and simulations to predict and optimize thermoforming effects. This innovation resulted in a lightweight, durable, and cost-competitive door, thereby advancing sustainable automotive manufacturing.
