For the establishment of carbon concrete in industrial practice, test methods for the reproducible determination of the mechanical properties of textile reinforcement structures are essential, especially the tensile strength. For this purpose, a novel test method was developed and qualified in the context of the research project C³-V1.2. With this method carbon fibre strands from flexible, stiff and conditionally ben-dable reinforcement laid webs can be characterized with regard to their tensile strength with little preparation effort and in a reproducible way.
