“…Once the component is wound, it needs to be cured in an oven to achieve its final mechanical properties. CFW requires an integrative design, engineering, and fabrication approach which relies on the interaction of physical prototyping, testing, and simulation due to the lack of building codes [12].…”

“…The design language of CFW is well suited for intricate framework structures, matching the property profile of such high-performance materials, but it is also optimal for lattices [13,14] and shells [15] in lightweight structural applications. Examples are found in recent technology demonstrators [12,16] and research trends, which are centered around integrated structural design and technical advancements [17][18][19] in fabrication and digital design.…”

Coreless filament winding is an emerging fabrication technology in the field of building construction with the potential to significantly decrease construction material consumption, while being fully automatable. Therefore, this technology could offer a solution to the increasing worldwide demand for building floor space in the next decades by optimizing and reducing the material usage. Current research focuses mainly on the design and engineering aspects while using carbon and glass fibers with epoxy resin; however, in order to move towards more sustainable structures, other fiber and resin material systems should also be assessed. This study integrates a selection of potential alternative fibers into the coreless filament winding process by adapting the fabrication equipment and process. A bio-based epoxy resin was introduced and compared to a conventional petroleum-based one. Generic coreless wound components were created for evaluating the fabrication suitability of selected alternative fibers. Four-point bending tests were performed for assessing the structural performance in relation to the sustainability of twelve alternative fibers and two resins. In this study, embodied energy and global warming potential from the literature were used as life-cycle assessment indexes to compare the material systems. Among the investigated fibers, flax showed the highest potential while bio-based resins are advisable at low fiber volume ratios.

“…It aims to assess multiple areas of research simultaneously and in constant exchange to enable mutual, fundamental innovation of the construction sector (Knippers et al, 2021). Novel building systems, such as coreless-wound fibre composite systems, and related manufacturing and engineering processes add additional challenges to the development of suitable collaboration strategies, stemming from geometric uncertainties involved in CFW (Gil Pérez et al, 2021). A project independent, open and interactive computational framework for co-design, not restricted to any specific project or component typology and easily expandable for the use across different scales was developed.…”

Fibrous architecture constitutes an alternative approach to conventional building systems and established construction methods. It shows the potential to converge architectural concerns such as spatial expression and structural elegance, with urgently required resource effectiveness and material efficiency, in a genuinely computational approach. Fundamental characteristics of fibre composite are shared with fibre structures in the natural world, enabling the transfer of design principles and providing a vast repertoire of inspiration. Robotic fabrication based on coreless filament winding, a technique to deposit resin impregnated fibre filaments with only minimal formwork, as well as integrative computational design methods are imperative to the development of complex fibrous building systems. Two projects, the BUGA Fibre Pavilion as an example for long-span structures, and Maison Fibre as an example of multi-storey architecture, showcase the application of those techniques in an architectural context and highlight areas of further research opportunities. The highly interrelated aesthetic, structural and fabrication characteristics of fibre nets are difficult to understand and go beyond a designer’s comprehension and intuition. An AI powered, self-learning agent system aims to extend and thoroughly explore the design space of fibre structures to unlock the full design potential coreless filament winding offers. In order to ensure feedback between all relevant design and performance criteria and enable interdisciplinary convergence, these novel design methods are embedded in a larger co-design framework. It formalizes the interaction of involved interdisciplinary domains and allows for interactive collaboration based on a central data model, serving as a base for design optimisation and exploration. To further advance research on fibre composites in architecture, bio-based materials are considered, continuing the journey of discovery of fibrous architecture to fundamentally rethinking design and construction towards a novel, computational material culture in architecture.

“…Despite these technological advantages [21], the industrial application of RCFW is not immediately possible in the building sector, as regulatory obstacles still have to be overcome in each individual case. These requirements and approvals in individual cases require an approval process, which is currently accompanied by full-scale testing [22] due to the limited ability to reliably simulate such structures numerically, since the fabrication methodology is new. In Germany, such an approval process can differ between federal Figure 1.…”

A hemispherical research demonstration pavilion was presented to the public from April to October 2019. It was the first large-scale lightweight dome with a supporting roof structure primarily made of carbon- and glass-fiber-reinforced composites, fabricated by robotic coreless filament winding. We conducted monitoring to ascertain the sturdiness of the fiber composite material of the supporting structure over the course of 130 days. This paper presents the methods and results of on-site monitoring as well as laboratory inspections. The thermal behavior of the pavilion was characterized, the color change of the matrix was quantified, and the inner composition of the coreless wound structures was investigated. This validated the structural design and revealed that the surface temperatures of the carbon fibers do not exceed the guideline values of flat, black façades and that UV absorbers need to be improved for such applications.
