Tessellation of carbon fibre grid reinforcements | Funding Period 2
The architecture of the textile reinforcement allows its properties such as strength, bending stiffness, and draping behavior to be determined during the manufacturing process. After the textile structure has been produced, these properties can be further influenced by a variety of finishing processes and the textile systems can be functionalized. Our aim is to enable novel approaches to the shaping of textile fabrics in order to extend the achievable shapes of carbon-reinforced concrete elements through tessellation. Tessellation describes the construction of periodically repeating patterns that are built up from simple basic geometric shapes. In order to realize these complex geometries flexibly and at the same time achieve good mechanical properties of the reinforcement, the approaches investigated in period 1 of TRR 280 – time-delayed curing in the prepreg approach or thermally induced softening in the organosheet approach – are applied.
The central aspect of the research is the analysis of the dependencies of manufacturing and structural parameters of the textile reinforcement on the draping behavior. Particular attention is paid to shear, compression and lane formation in the curvature area of the tessellation and the mechanical behavior under tensile and compressive load. In addition to research on the material side, manufacturing approaches for large-scale mosaic-like reinforcement structures are also being investigated.

Investigation of New Material and Technology Approaches for Continuous Inline-Forming and Consolidation of Textile Reinforcements | Funding Period 1
New, digital and continuous production methods (e.g. 3D concrete printing and concrete extrusion) allow for load-path-adapted (form follows force) and thus material-minimized constructions. However, conventional impregnated textile reinforcements are not suitable for integration into these manufacturing processes for the production of complex carbon-reinforced concrete structures. The main reason is the loss of a large part of the form flexibility due to the established offline consolidation. Project B02 therefore investigates the targeted temporal shift of the forming and consolidation step using prepreg systems into the concreting process and its applicability in the course of the new, digital and continuous manufacturing processes. In addition to established curing mechanisms such as heat or UV radiation, new approaches, such as activation via the alkalinity of the concrete, microwaves and induction, for inline production of carbon-reinforced concrete are investigated.
Within the framework of B02, the seed fund project "Carbon-reinforced concrete structures additively manufactured on free-standing textile formwork – freeDome" (1st round 2022) is carried out together with project D01.
