The Experimental And Theoretical Research On Carbon Fiber Reinforced Cement's Properties

Carbon fiber reinforced cement is a combination of advanced reinforcing materials and traditional architectural materials. At first, this paper introduces carbon fiber's properties and structure, then it introduces the preparation of short carbon fiber reinforced cement and continuous carbon fiber reinforced cement. The experiment used carboxylmethyl cellulose as a dispersion and made a reasonable process of stirring to solve the problem of carbon fiber's well-proportioned existence in the matrix. The experiment also gained the relationship between composites' compressive strength and carbon fiber's content, the relationship between composites' splitting strength and carbon fiber's content and the relationship between composites' splitting strength and carbon fiber's length. Additionally, the experiment used short polyacrylonitrile fiber to do some research and found its composites' property is better than carbon fiber's. After these work, the experiment used continuous carbon fiber to reinforce cement and found the factors that influence its composites' properties, such as carbon fiber's content and carbon fiber's mode of laying. According to the experimental phenomenon, this paper analyses the mechanism of fiber reinforced cement with the elementary theory hi being. By a data processing, it gains the fitting curves between composites' strength and fiber's content in different conditions. At last, this paper introduces the electric properties, thermoelectric properties and smart properties of carbon fiber reinforced cement with others' results and looks into the future of carbon fiber reinforced cement's application.
