This paper presents a novel biomimetic approach to the kinematics of deployable systems for architectural purposes. Elastic deformation of the entire structure replaces the need for local hinges. This change becomes possible by using fibre-reinforced polymers (FRP) such as glass fibre reinforced polymer (GFRP) that can combine high tensile strength with low bending stiffness, thus offering a large range of calibrated elastic deformations. The employment of elasticity within a structure…

The application of flexible materials for convertible structures in architecture and the use of bending deformation in these structures have been new topics in recent years. The importance of bending

Hindwings of insects as concept generator for hingeless foldable shading systems

In insights into biological findings and the development of a deployable structure inspired by the Flexagon model of hindwings of insects in general and the hierarchical structure of the wing cuticle of the shield bug (Graphosoma lineatum), which is partially transferred into a multi-layered structure with locally adapted stiffness.

Deformation Behavior of Elastomer-Glass Fiber-Reinforced Plastics in Dependence of Pneumatic Actuation

The bending angle increases with decreasing material stiffness and with increasing hinge width, while it is not affected by the flap stiffness itself, according to a finite element model software workflow.

Flectofold—a biomimetic compliant shading device for complex free form facades

Drawing inspiration from the hinge-less motion of the underwater snap-trap of the carnivorous waterwheel plant, the compliant facade shading device Flectofold was developed and the actuation principle of the plant can be identified.
