Leichtbau BW Installation, Hannover Fair 2014
Carbon fibre reinforced composite surface structure
The Leichtbau BW Installation has been designed by the Institute for Computational Design (ICD) and the Institute for Building Structures and Structural Design (ITKE). It forms a central exhibit at the BW-I and Leichtbau BW stand at this year’s Hannover Fair, the biggest industry fair worldwide. The spatial installation is constructed from carbon fiber reinforced composite surfaces and aims at demonstrating Baden Wuerttemberg’s competence in lightweight construction in research and industry.
The design of the installation is based on advanced computational design, simulation and fabrication of composite structures. It utilizes new technologies of tailored fiber placement adopted from the aerospace industry in combination with computational design strategies and structural simulation. The carbon fiber layout is generated through a structural topology optimization, machine constraints and lamination requirements. In the resultant translucent structure the black carbon fibers not only enable a lightweight system but also create a striking surface articulation that exposes the constructional logic to the fair visitors. The semi-transparent structure divides the exhibit into various communication zones with different characters including: an integrated information bar, a small semi-enclosed seating area and a larger marquee which extends into the air for visibility from a distance.
In collaboration with the Institute of Aircraft Design (IFB) a tailored fiber placement process was used. This method uses a computer controlled fiber placement head to sews carbon fiber rovings onto a glass fiber fabric. This allows precisely controlled fiber arrangements. The stitched carbon rovings structurally reinforce the thin, translucent GFK panels.
The Leichtbau BW Installation has been exhibited at the Hannover Fair from 7th – 11th of April 2014.
