Experimental Study On Bending Strengths Of The Concrete Plates Reinforced By Carbon Fiber And Wire Textile

Carbon fiber has a high tensile strength, being woven into a network can effectively improve the tensile strength of concrete structures. Using carbon fiber textile and wire together, can improve the flexural capacity and deformation capacity of concrete structures. This paper focuses on the bending strength of amount of concrete plates reinforced by carbon fiber textile and carbon fiber with wire textile in a different grid spacing of100mm carbon fiber material, and compared with plain concrete plate, wire concrete plate.The tests showed that the bending strength can be remarkably improved by concrete plates reinforced by carbon fiber textile and carbon fiber with wire textile, reinforced by carbon fiber with wire textile, the bending strength was the most obvious, and the ability to resist deformation was better than the effect of carbon fiber textile. Compared with plain concrete plate, the bending strength of carbon fiber textile reinforced concrete plates in16,24,32,40bundle, were increased by26.8%,43.2%,90.1%,92.5%, and the deformation were improved by69.2%,243.9%,291.2%,372.5%. And the bending strength of carbon fiber with wire textile reinforced concrete plates in16,24,32,40bundle, were increased by59.6%,69.0%,111.3%,130.0%, and the deformation is raised62.6%,218.7%,253.8%,323.1%. Compared with carbon fiber textile reinforced concrete plates, the concrete plates reinforced by carbon fiber with wire textile in32,40bundle, the bending strength were improved by11.1%,19.5%, and the deformation reduced by9.6%,10.5%.In a different number of carbon fiber bundle, the flexural capacity of components increases with carbon fiber, the flexural capacity of concrete structures reinforced by carbon fiber textile is more obvious in32,40carbon fiber bundle. Concrete plates reinforced by carbon fiber textile and carbon fiber with wire textile in32bundle, compared to24, the bending strength were increased by32.8%,25%, and the deformation increased cross-displacement by13.7%,11.0%. The40units compared to32of the two boards, the bending loads were increased by1.2%,8.9%, and the deformation increased cross-displacement by20.8%,19.6%, it indicated that the enhancement of concrete plate reinforced by carbon fiber textile of was not obvious,when the number of carbon fiber bundle increases to a certain value.
