Zugtragverhalten von Betonbauteilen mit getränkter Textilbewehrung aus Flachsfasern

Abstract: In der letzten Zeit haben Naturfasern aufgrund ihrer umweltfreundlichen, wirtschaftlichen und mechanischen Eigenschaften bei der Verwendung als Verstärkung in Verbundwerkstoffen ein wachsendes Interesse in der Forschung geweckt. Trotz dieser Vorteile wurde das Tragverhalten von textilen Bewehrungen aus Naturfasern in Betonbauteilen bisher nicht systematisch untersucht. Die für Textilbetonbauteile entwickelten Bemessungsregeln beschränken sich deshalb auf textile Bewehrungen, die aus synthetischen Fasern herges… Show more

“…This premature failure was due to the steel plates causing notch stresses and due to the poor bond behaviour between the smooth epoxy-covered zone on the steel plates, the concrete matrix and, ultimately, the textile reinforcement (Figure 6). Such behaviour was not identified during preliminary tests conducted with this reinforcement type [55,62]. It should be stressed here that failure in the free measuring length could occur due to either shortening the steel plates or thickening the heads of the test specimen.…”

“…The tensile tests were conducted on bone-shaped test specimens that were already used in comparable tests on concrete components with conventional synthetic fibres [8,[59][60][61][62]. Since the non-impregnated textile made of natural flax fibres has a larger cross section than textiles made of conventional synthetic fibres, the web thickness in the free strain length was increased from 10 mm to 15 mm.…”
