To study further mechanical behavior of flexural members of carbon fiber reinforced concrete, this text uses the methods of fiber materials composite principles and balance equations, and derives the elastic modulus of the carbon fiber concrete. The acting principle of carbon fiber in the concrete is analyzed. Based on three bearing stages of carbon fiber reinforced concrete beam, the calculation formulas to flexural bearing capacity of carbon fiber reinforced concrete are given. It is theoretical basis of implication of carbon fibers in civil engineering.

In this paper, in order to simulate the corrosion of seawater, the drying-wetting cycling test was used. The mechanical properties of carbon fiber-reinforced concrete beam under salt damage were studied and the reinforcement effect of the CFRP was analyzed. At the same time, the bearing capacity of cross section of CFRP strengthened PC beam under corroded was analyzed.

This paper analyzed the cracking behavior of carbon fiber reinforced concrete beam under static load using the finite element numerical analysis. By the way of finite element numerical simulation and the method of increasing the load gradually to analyze the carbon fiber content influence on the beam cracking, crack developing, beam deflection and beam average crack spacing. By comparing with the simulation result of common reinforced concrete beam test piece, it turned out that the carbon fiber reinforced concrete beam has a good cracking and deformation behavior under the same ratio of reinforcement. Under the same load, both the carbon fiber reinforced concrete beam and the common reinforced concrete beam have a small deformation, but the carbon fiber reinforced concrete beam showed a better resistance to deformation as the load increasing, its deflection increasing extent showed an obvious decrease compared with that of the common reinforced concrete beams. Its crack width can be revised by the common reinforced concrete beam rules.

Carbon Fiber Sheet

In this paper, it makes a preliminary study on the material of carbon fiber sheet to reinforce rough sleeper beam in order to enhance the magnitude of ultimate flexural bearing capacity. Considering the actual construction technology and environment, four reinforced concrete sleeper beams are used to experiment simulation to study the influence of carbon fiber sheet to ultimate flexural bearing capacity of reinforced concrete structures. Experiment results show that pasting two layers of carbon fiber sheet under reinforced concrete beam can have about a 25% increase in flexural bearing capacity.
