Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 5483454
The stress-oriented arrangement of fibre materials, such as glass or carbon, which have an excellent load-bearing capacity, leads to technical textiles that may be incorporated into a concrete matrix. So a new, innovative composite material is produced, which can be used for the production of new concrete members and also for the restoration and strengthening of existing structures. As the materials used are noncorrosive compared to steel and as they show great strength at the same time, textile-reinforced concrete can be used for strengthening tasks of small dimensions. With regard to timber structures, textile reinforcement can compensate the strength and stiffness differences caused by anisotropy and can increase durability. If textile structures are used instead of steel gussets this may lead to a considerable increase in the ultimate strength and the ductility of joints.
The five fields of the project are designed that theoretical and experimental investigations are carried out to provide the fundamentals of the materials. Additionally information will be obtained about the mechanical description, the detailing and the dimensioning, the techniques of applying, the realisation on the site and the long-term behaviour. All leading to a safety concept and also a service life concept for the use of textile reinforcements for restoration and strengthening.
