Item Open Access Extension of computational co-design methods for modular, prefabricated composite building components using bio-based material systems(2023) Zechmeister, Christoph; Gil Pérez, Marta; Dambrosio, Niccolo; Knippers, Jan; Menges, AchimRobotic coreless filament winding using alternative material systems based on natural fibers and bio-based resin systems offers possible solutions to the productivity and sustainability challenges of the building and construction sector. Their application in modular, prefabricated structures allows for material-efficient and fast production under tightly controlled conditions leading to high-quality building parts with minimal production waste. Plant fibers made of flax or hemp have high stiffness and strength values and their production consumes less non-renewable energy than glass or carbon fibers. However, the introduction of natural material systems increases uncertainties in structural performance and fabrication parameters. The development process of coreless wound composite parts must thus be approached from the bottom up, treating the material system as an integral part of design and evaluation. Existing design and fabrication methods, as well as equipment, are adjusted to emphasize material aspects throughout the development, increasing the importance of material characterization and scalability evaluation. The reciprocity of material characterization and the fabrication process is highlighted and contributes to a non-linear, cyclical workflow. The implementation of extensions and adaptations are showcased in the development of the livMatS pavilion, a first attempt at coreless filament winding using natural material systems in architecture.Item Open Access Toward reciprocal feedback between computational design, engineering, and fabrication to co-design coreless filament-wound structures(2024) Kannenberg, Fabian; Zechmeister, Christoph; Gil Pérez, Marta; Guo, Yanan; Yang, Xiliu; Forster, David; Hügle, Sebastian; Mindermann, Pascal; Abdelaal, Moataz; Balangé, Laura; Schwieger, Volker; Weiskopf, Daniel; Gresser, Götz T.; Middendorf, Peter; Bischoff, Manfred; Knippers, Jan; Menges, AchimItem Open Access Co-design of a natural fiber-timber hybrid structural system using dual-robot coreless filament winding(2026) Duque Estrada, Rebeca; Kannenberg, Fabian; Chen, Tzu-Ying; Guo, Yanan; Knippers, Jan; Menges, AchimThis paper presents the co-design methods for a new hybrid load-bearing system as a strategy for advancing bio-based architecture. Timber and natural fiber polymer composites (NFPC) are combined into a hybrid system, offering opportunities to leverage their strengths while balancing the use of natural resources. The system performs synergistically, with each material fulfilling complementary roles. Timber extrapolates its structural function by acting as an embedded frame for the fibers to be wound on. The paper presents computational methods designed to optimize material performance while integrating functionalities and fabrication opportunities. A dual-robot winding method is presented as a solution for balancing winding tension in the structure during fabrication. The hybrid system is demonstrated through the design and construction of a pavilion, the first to combine flax fibers with a partially bio-based resin and timber into a dual-robotically fabricated structure on an architectural scale. The project represents further advancements in multi-robot fabrication and a novel material approach toward bio-based hybrid systems in architecture.
