The related methods to determine the mechanical properties such as tensile strength and elastic modulus of carbon fiber fabrics are discussed.The experimental research and computer simulation of five reinforced carbon fiber reinforced concrete beams are carried out.The experimental data and analytical data are in accordance with It shows that the measured mechanical properties of carbon fiber fabric is reliable and reasonable.At the same time, based on the analysis of the test data, the simplified design formula of the normal section bearing capacity of reinforced concrete flexural members reinforced by carbon fiber fabric is obtained.
