Abstract
The presented work investigates the design and manufacturing of a three-dimensional structure using bio-based materials and Coreless Robotic Filament Winding (CRFW) technology. The primary material is flax, chosen for its sustainability, impregnated with partly bio-based epoxy resin. The study aims to address environmental impact and labor shortages in the construction industry by optimizing the design and manufacturing of a structural element capable of withstanding axial compressive forces. The digital design process utilized Rhinoceros and Grasshopper software, with optimization through Karamba3D and Octopus plugins. Three final design options were manufactured using the ABB IRB 1200-5/0.9 robot, winding impregnated flax rovings into a 3D structure without auxiliary structures. After manufacturing, the structures were post-cured and calibrated using a numerical model in Oasys GSA to simulate the construction process and understand structural behavior during winding and a numerical model in Karamba3D to simulate the compression tests. Axial compression tests on the structures revealed maximum compressive forces of 28.5 kN, 15.34 kN, and 16.69 kN for the three options respectively. Numerical results showed significant differences due to material properties, fabrication imperfections, and test conditions. Despite these differences, the research demonstrates the feasibility of optimized design using robotic filament winding with bio-based flax fibers. Further research is needed to address manufacturing challenges and assess the suitability of this technique for large-scale structural applications.
