| Résumé : |
Building in a resource-saving way and still exploiting a high performance potential, is that even possible ? Composite optimized profiled textile reinforcements for concrete applications and the related manufacturing technology were developed at the ITM. On the basis of braiding and for-ming technology, a new generation of profiled reinforcement yarns was developed with the help of simulation-based investigations. Like ribbed steel reinforcements, these profiled yarns have a very high bond with the concrete matrix, but despite the profiling they almost fully exploit the performance potential of the carbon fibers in terms of tensile properties. In this way, the bond length required for complete force transmission between the textile reinforcement and the concrete can be reduced to just a few centimeters, and up to 80% of the component-dependent over-sizing of the textile reinforcement can be saved. The further development of the multiaxial warp knitting technology for the requirement-based and fiber-friendly processing of the profiled yarns into grid-like reinforcement structures enables the production of profiled textile reinforcement structures with the highest bond properties for use in carbon-reinforced concrete components with maximum material and resource efficiency. |
