Abstract
Given the constraint of curved-crease paper folding, which type of sheet-structure with compliant hinges can be designed and fabricated? This paper investigates mirror reflections of developable surfaces for structures and provides the results of proof-of-concept prototypes that demonstrate how this specific topic in geometry can be used to create stiff surface structures. The specific method to create curved creases is based on mirror reflections of cylinders, cones and tangent surfaces, which can be constructed with CAD software. The goal of the presented case studies is to highlight design principles and tectonic solutions related to 2D manufacturing. This paper reports on projects such as a single surface shell, furniture designs, building parts and a double surface structure, all made of vulcanized fibre sheets. The material is made of polymerized cellulose and is available in large sheets. The material becomes malleable when it is wet, which enables the folding of compliant hinges. The findings of the built projects provide tectonic solutions that relate this topic in geometry to the logics of sheet assemblies.
