FLECTOFOLD Demonstrator, BauBionik Exhibition, Natural History Museum, Stuttgart, 2018


 

 

FlectoFold is an Elastic-Kinetic Facade Shading System. It is modular and made of Materially-Graduated FRP.

This large-scale demonstrator highlights the potential of Flectofold for application on complex architectural surfaces, exhibits the kinetic performance of pneumatically-actuated and materially-graduated FRP laminates and explores the possibilities of active and autonomous modes of control and operation.

It consists of 36 Flectofold modules. Each Module Covers an area of approximately 1 m2 and has an integrated Pneumatic cushion. Once pressurized (0.04 – 0.09 Bar), the cushion induces elastic bending onto the body of the Materially-graduated FRP Laminate, and as a result generate movement and transformation. The modules are propagated on an anticlastic guiding surface and the steel sub-structure support them in space, aligns them accurately on the guiding surface, and provides all necessary detailing for integration of pneumatic actuators. The control system enables the driving of modules in an individual or synchronized fashion, based on active user input or pre-programmed sequences.

Flectofold was exhibited as part of the BauBionik Exhibition from 17.10.2017 to 01.05.2018 at the Natural History Museum in Stuttgart, Germany.
