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.

纤维材料（如玻璃或碳）的应力取向排列具有优异的承载能力，导致技术纺织品可能被纳入混凝土基质中。因此，一种新的、创新的复合材料被生产出来，它可以用于生产新的混凝土构件，也可以用于修复和加强现有结构。由于所使用的材料与钢相比没有腐蚀性，同时又表现出很高的强度，因此纺织钢筋混凝土可以用于小尺寸的加固任务。对于木结构，织物加固可以补偿各向异性引起的强度和刚度差异，提高耐久性。如果使用纺织结构代替钢扣板，这可能会导致接头的极限强度和延展性的相当大的增加。
