Abstract: The use of textile reinforcements for building applications has been on the rise since some years now (e.g. as plaster or floor reinforcement). One of the most sustainable developments is textile reinforced concrete (TRC). TRC can save up to 80 % of concrete as com-pared to a steel reinforced structure for similar applications [1]. A biaxial warp knitted structure, made with AR-glass or carbon fibres, increases the mechanical properties of concrete components significantly. On the basis of its non-corrosive property, building components with TRC can be realized with very thin cross-sections and with a high bearing capacity. A significant advantage of TRC is the formability of the textile reinforcement. Curved TRC-elements of high quality finish are possible due to the inherent drapability of the textile in comparison to steel reinforcement. The minimum radius of the curve decides the required level of drapability of the textile. The drapability of a biaxial warp knitted tex-tile is mainly depending on the stitching pattern (for e.g. pillar, tricot or plain). Textiles which use the “pillar” stitching pattern have a higher stiffness compared to a “plain” knit-ted textile. In the course of a public funded project we want to realize locally adapted textiles which combine two different levels of drapability in one single fabric. The overarching aim is generating the possibility to manufacture adapted textiles for special folded ele-ments. A major challenge is to classify the possible combinations of stitching patterns to determine their influence on the drapability of the textiles on basis of a cantilever test. The public funded project “ConcreteFold” started in June, 2014 and has a 2 years research period. This paper will present the project scope as well as the first results.
