Self-morphing of thin plates could greatly impact the life if used in
architectural context. Yet, so far, its realizations are limited to small-scale
structures made of model materials. Here, new fabrication techniques are
developed that turn two conventional construction materials—clay and fiber
composites (FRP)—into smart, self-morphing materials, compatible with
architectural needs. Controlled experiments verify the quantitative connection
between the prescribed small-scale material structure and the global 3D
surface, as predicted by the theory of incompatible elastic sheets. Scaling up
of desired structures is demonstrated, including a method that copes with
self-weight effects. Finally, a method for the construction of FRP surfaces with
complex curvature distribution is presented, together with a software
interface that allows the computation of the 3D surface for a given fiber
pattern (the forward problem), as well as the fiber distribution required for a
desired 3D shape (the inverse problem). This work shows the feasibility of
large-scale self-morphing surfaces for architecture.
