Double-curved textile reinforced concrete facade

15.01.2019 Textile reinforced concrete (TRC) elements have so far only been used as flat panels, flat sandwich structures or simply curved building structures. As part of the research project "CurveTex - Development of a drapable textile reinforcement for the production of double-curved textile reinforced concrete elements", the world's first double-curved TRC facade was realized.

The cooperation took place between the Institut für Textiltechnik (ITA) of RWTH Aachen University, Penn Textile Solutions GmbH, Paderborn/Germany and Stanecker Betonfertigteilwerk GmbH, Borchen/Germany.
Based on the expertise of Penn Textile Solutions in the production and development of elastic textiles, a drapable reinforcement textile could be developed in this project. Standard textiles could not be used for the production of double-curved textile concrete elements so far, as either undesired wrinkling occurred or the fibers had to be cut through. Research within the CurveTex project has resulted in a high geometric freedom of design without wrinkling.
The result of the project was a demonstrator facade made of 12 filigree textile reinforced concrete facade elements.
