This was achieved by diminishing the required formwork of state-of-the-art filament winding to discrete boundary frames. Then, impregnated fibers are wound between them, forming lightweight lattice structures. A series of pavilions at the University demonstrated the system's potential and enabled the transfer of CFW into practice, bringing along other engineering challenges, such as the requirement to prove structural integrity and safety. The BUGA Fibre Pavilion was the first long-span application using CFW. In this project, a series of full-scale structural tests successfully proved the structural capacity of the composite components. Maison Fibre expanded the research toward multi-story building systems and explored the combination of CFW components with timber plates as hybrid slabs. To improve the sustainability aspects of the system, the LivMatS Pavilion replaced the previously used carbon and glass fibers with natural fibers. This pavilion achieved different materiality, showing the potential of bio-composite filament wound structures. This paper describes and compares the design and engineering process in each system: long-span, hybrid slab, and natural fiber components, and reveals the potential and future research goals to achieve more sustainable building systems using CFW structures.
