Hybrid-Active Winding - A novel filament winding approach leveraging an embedded bent timber winding frame towards a synergetic hybrid module
Fiber-polymer composites (FPCs) offer a number of performative qualities for their application into the building industry, including high load-bearing capacity despite minimal self-weight, as well as an inherently integrated design-to-fabrication workflow. Since the development of the coreless filament winding (CFW) fabrication method at the Institue for Computational Design and Construction (ICD) at Universität Stuttgart, the need for engineered fabrication frames has been recognized as an onerous but required element, built to provide rigidity against high tension forces present throughout robotic winding. Ongoing research in this field has explored fabrication strategies towards minimizing these frames, however, has scarcely explored the potential of utilizing the frame in the resulting fabricated element. Furthermore, few projects have addressed the architectural functionality limitations of elongated FPC elements by exploring their applicability in a hybrid material system with a surface element. Hybrid-Activated Winding presents a novel fabrication method for coreless filament winding through the integration of an embedded thin timber winding frame, present not only in fabrication but in the resulting wound element. Leveraging the elastic behavior of thin timber, the developed method offers an alternative means of tensioning fibers, allowing passive tensioning through bending and releasing bent-active timber. The result is a thin timber and FPC discrete hybrid building module with an integrated connection detail, enhancing the fabrication, functionality, and performance potential of both materials through this hybridization.
