Project summary:

Weaver bird nests, an inspiration for the architecture of tomorrow

Weaver birds are remarkable builders: their nests, woven from plant fibres, are both strong and lightweight. Their resistance relies on two simple mechanisms: the flexibility of the fibres and the friction between them at contact points. This project draws on this natural ingenuity to better understand the physics behind these woven structures.

Laboratory experiments will be conducted to study, in a controlled way, how assemblies of woven fibres or rods behave mechanically. The aim is to identify the fundamental rules governing their strength, so that these principles can then be applied at a larger scale.

Ultimately, this knowledge will be used to design real architectural elements such as woven panels or shells, combining lightness and robustness. The project brings together mechanics specialists and architect-researchers, offering an original bridge between science and architecture within PSL institutions.
