Textile Strukturen zur Bewehrung zementgebundener Matrices

As a complement to shortfibre reinforced air-placed concrete, textile reinforced concrete elements present new applications in the area of thin-walled elements, due to their high strength resitance. By physical and chemical examinations fibermaterial is detected, which on principle is suitable for the reinforcement of concrete elements. For an optimum exploitation of the strength of reinforcement fibres, like Carbon-, alkaline resistant Glass- and Basaltfibers, it is necessary to develop processes, which enable of manufacture load-controlled reinforcement textiles. On principle manufacturing methods for planar textiles, like special lenofabrics and lattice-like multiaxial-multiply-fabrics are developed. For the production of threedimensional reinforcement textiles, a double wall warp knittting machine and a circular warp knitting machine are presented. Since the fiber effectivity of a reinforcement textile only can partially be utilized, the bonding behaviour to the cementious matrics is tested in dependance on the following parameters: Thread distance, Cross section geometry of rovings, Coating material and Sizing. All textile structures are described with one function of the program MATLAB. These structural modellings can be taken as a foundation of a FE-simulation. According to three examples of different applications, the economic efficiency of the manufacturing process of shortfiber reinforced air-placed concrete is compared to a textile reinforced alternative. In these cases the economic efficiency can be assessed separately for small-lot production and industrial scale manufacturing.
