Abstract

This paper presents an integration of level set-based anisotropic topology optimization and 3D printing for designing continuous carbon fiber (CCF)-reinforced polymer composite structures. During the optimization process, geometric boundaries of the composite structure are updated by solving a reaction–diffusion equation. Based on these boundaries, the fast marching algorithm is employed to generate tailored CCF paths across the structural domain. This approach ensures consistency of the fiber path layout in the numerical topology optimization and the corresponding 3D-printed model. To validate performance, the 3D-printed composite structure using tailored CCF paths is compared with structures using fixed fiber paths orientations of 0°, 30°, 45°, and 60°, respectively. The numerical findings closely align with the experimental results for all study cases. Furthermore, the topology-optimized structure with tailored CCF paths exhibits superior performance.

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
