Fibre-Wound Bio-Composites
Led by Professor Marta Gil Pérez, the research line on Fibre-Wound Bio-Composites for Resourceful Architectural Structures (FIBRAS) explores a promising solution through the use of fibre-polymer composite structures manufactured via robotic filament winding. These lattice composite structures offer high-performance, lightweight alternatives that substantially decrease material consumption. Moreover, digital fabrication techniques help minimise waste while enhancing design efficiency and production processes.
DEVELOPING SUSTAINABLE BUILDING ELEMENTS
The FIBRAS research group aims to transform material-efficiency strategies into comprehensive eco-effectiveness approaches, enabling the design of sustainable structural systems with bio-based materials and bridging the gap between research and industry. It encompasses various initiatives, including funded research projects, graduation theses, and PhD studies, reflecting a multidisciplinary approach to addressing one of the construction industry's most pressing issues.

SUSTAINABLE STRUCTURAL DESIGN
To fully achieve sustainable structural design, the research will evolve to embrace circularity principles—narrowing, slowing, and closing the resource loop—translating into strategies of “use less,” “use longer,” and “use again.” Key areas of focus include:
- Material Selection: Investigating various emerging bio-based fibre composites, suitable fabrication techniques, and material characterization strategies that align with fabrication methods, complemented by life cycle assessment feedback.
- Computational Design Workflow: Implementing a design workflow that integrates structural design, simulation, and fabrication feedback with relevant disciplines, enhancing system simulation and characterization to reduce material usage.
- Reliability and Durability: Improving the reliability and durability of novel structural systems through monitoring and standardization methods essential for high-uncertainty structures. These methods will also facilitate structural calibration, further optimizing design and material consumption. Standardization efforts will focus on creating and gathering structural data to enhance structural codes, such as the Eurocode.
- Reuse and Recycling: Considering reuse and recycling from the early design stages. Bio-based material systems present opportunities for cascading strategies that maximize resource effectiveness. For example, standardized modular structures can follow a design for disassembly approach, enabling system reuse. Other recycling strategies will also be explored to achieve full material energy recovery.
EXPERIMENTAL WORK
FIBRAS embraces an experimental approach rooted in structural engineering principles to advance the use of fibre-wound bio-composites. Our work focuses on developing and refining a custom robotic filament winding setup—including a bespoke impregnation system—to improve fabrication control, consistency, and performance.
Structural behaviour is at the heart of our investigations. We prototype and test specimens to evaluate mechanical properties such as tensile strength, stiffness, and load-bearing capacity. This hands-on research is essential for understanding the variability and anisotropy of bio-based composites, which often behave unpredictably under load.
By integrating mechanical testing with design and fabrication, we generate the structural data needed to inform reliable modelling and simulation. Our goal is to establish engineering principles for these emerging materials and contribute to performance-based design standards that support their use in sustainable construction.
