Abstract: Textile reinforcements made of materials such as carbon and glass fibres meet the growing requirements for corrosion-free and high-strength lightweight structures in the building industry. One of the most sustainable developments is textile reinforced concrete (TRC). The high formability is one of the challenging advantages of TRC structures compared to steel reinforced concrete. The inherent drapability of textile reinforcements allows the production of folded and/or double curved TRC elements with a high-quality finish. The minimum radius of the curve decides the required drapability level of the textile. The textile manufacturing process of warp knitting allows substituting single threads and changing of the stitch type during production. This makes warp knitting suitable to achieve the goal of locally adapted reinforcing textiles. This paper will present the results of a completed public funded project "Concrete Fold" in which possible combinations of stitching patterns were classified to determine their influence on the drapability of the textiles on basis of a cantilever test. Furthermore, the paper will give an overview about the scope of another public funded project "CurveTex" as a follow-up research where the manufacturing of double curved TRC elements through a combination of elastic and high modulus fibres is pursued.
