MUSE MyceliUm SEat - Developing Mycelium-Based Materials with Enhanced Durability, Adaptable Design, and Natural Colouration for Automotive and Architectural Applications

This research explores mycelium-based composites (MBCs) as regenerative, bio-integrated materials for architectural and product design. Responding to the urgent need for sustainable construction alternatives, the project examines how fungal materials can transition from experimental novelty to functional application. Launched in autumn 2024, the R&D project “MUSE – MyceliUm SEat” investigates underexplored fungal species, environmental growth parameters, and fabrication techniques to expand the architectural potential of mycelium. At the centre of the study is a racing car seat prototype developed for Formula Student competitions, chosen for its stringent ergonomic and structural requirements. The car seat serves as a case study to evaluate the mechanical performance of various MBC formulations in extreme conditions. Materials are developed and tested in collaboration with microbiologists and material scientists, following an iterative and practice-based methodology. The result is a material matrix categorising fungal species, substrate types, and fabrication methods, supporting tailored applications across design scales. To diversify aesthetic and structural outcomes, the project moves towards testing different material combinations and assemblies, beyond the typical mono-material use. Techniques such as moulding, 3D printing, and fabric forming are assessed for their influence on finish, strength, and form. Initial findings show that MBCs can meet high-performance demands, with potential applications in architecture, interior design, and furniture. Beyond sustainability, mycelium is positioned as an adaptive material system - capable of forming biohybrid structures with unique surface qualities, lightweight strength, and biodegradability - offering a new material language for future integrative design.
