요약Intro: Due to the climate emergency, our world is subject to changes almost every day. The building industry has the biggest share of carbon emissions, so architects and designers must conform to the change and shift the design and manufacturing paradigms accordingly. The importance of materials and their role in the design and manufacturing of any physical object is undeniable. Our approaches to using and forming materials might be the key to conforming to the ever-changing world. In contrast to the common understanding of the relationship between form and matter in design and making, there is a less-practiced approach that values the uncertainties in the processing of the materials. In this approach, the hylomorphic model of creation is challenged. In hylomorphism, form is the substantial part of making and gives the essence and identity to the matter. However, this alternative approach does not separate form and matter (Gursoy, 2016). Background: Biomaterials are materials made from living organisms that frequently exhibit exceptional mechanical and more sustainable qualities compared to the weak components from which they are generated (Zolotovsky, 2018). The hierarchy, self-assembly, and self-healing capabilities of biomaterials are among their most significant characteristics. However, there are certain obstacles to using biomaterials in the building sector: their uncertain nature and the unconventional methods used in their preparation limit their large-scale use. Therefore, innovative technologies that can improve the qualities of biomaterials with the least amount of alteration to their natural behavior are needed to advance their use in the building industry. These organisms often become co-designers when working with living organisms to cultivate biomaterials. Due to their inherent uncertainties, the design process may result in unexpected findings. On the one hand, designers cultivate biomaterials, which allows them to control their material properties as part of the design process. On the other hand, the intrinsic uncertainty of these materials often leads to unexpected discoveries in the design process. Thus, unlike traditional materials, the outcome is imposed not only by the designer but also by a dialogue between the designer and the living organism.Overview: This research focuses on the interrelationships between form, matter, and structural performance in addressing the challenges related to the inherent uncertainty of biomaterials and their use in architecture as structural elements, with a specific focus on mycelium-based composites. Mycelium-based composites are lightweight and biodegradable biomaterials obtained from the incomplete cultivation of the vegetative root of fungi on organic substrates. Fungi have an undeniable role in shaping our world: In addition to their agricultural and medicinal uses, they digest rock and create soil, digest contaminants, help feed plants, control animals' behavior, and modify the composition of the Earth's atmosphere (Sheldrake, 2020). Fungal biomaterials, specifically mycelium-based composites, can be cultivated on various organic substrates, including byproducts or waste of other industries and locally available resources. By implementing mycelium-based composites in temporary and low-rise constructions as alternatives for conventional load-bearing elements, it would be possible to decrease the amount of waste produced by the architecture, engineering, and construction (AEC) industry and reduce carbon emissions. Methodology: The methodology used for this dissertation is the prototypological framework. Prototypologies are full-scale applications that holistically discover all connected aspects and address unknowns of a specific question while being a part of a more extensive and systematic test series of such different typologies with similar characteristics but varying parameters. The prototypological methodology can help designers find the best practices for utilizing a novel material, technique, or combination (Heisel and Hebel, 2019).The study starts with a state-of-the-art literature review that studies using mycelium-based composites in various fields: Architecture and Design, Materials Science, and Biology. Then, through bottom-up studies, the effects of different cultivation parameters on the mechanical properties are analyzed. Following these tests, two prototypologies MycoCreate 2.0, and MycoKnit, have been designed and tested to address the gaps identified in the literature. MycoCreate 2.0 is a spatial funicular structure made of 64 load-bearing components formed with recyclable formworks. MycoKnit is a thin-shell structure designed with components cultivated with knitted textile-based materials and sacrificial formworks. Both prototypologies are designed to address the design challenge of WG 21 lightweight, innovative structures competition of the International Association of Shell and Spatial Structures. Finally, based on these prototypologies, new opportunities for enhancing the material cultivation process and novel material-forming techniques are discussed.Concluding Remarks: Unconventional materials and techniques are still under development in the lab and studio environments and seem far from large-scale industrial functions. However, they seem promising in addressing many of the challenges of our era, such as population growth, global warming, and the depletion of natural resources. This study barely touched the surface of a profound concept that lets architects and designers see some novel outcomes. This field of research seems promising and undeniable for shaping the future of materials and architecture. This research is a step forward in understanding how to work with these materials and techniques and take advantage of these sustainable alternatives for the future.
