Carbon fiber is a high carbon content at the same time with high strength and high modulus fiber of the new fiber material is also due to the characteristics of the new material, making the building structure reinforcement has a role to be underestimated. Our common application and building reinforcement in the carbon fiber material to belong to the carbon fiber cloth.
1) the tensile strength of fibrous composites standard value, elastic modulus and ultimate elongation;
2) fiber fabric per unit area mass or preformed fiber volume content;
3) K number of carbon fiber fabric.
Note: The tensile strength of fibrous composites shall be determined according to the current national standard "Test method for tensile properties of unidirectional fiber reinforced plastics" GB / T3354, but the number of test pieces shall not be less than 15, and the test results shall be calculated Of the mean, the standard deviation and the coefficient of variation for the determination of its strength standard value;
The high strength and low density properties of carbon fibers also make their role in the reinforcement of the building structure. Therefore, the carbon fiber materials are often used in buildings where the load is increased, the engineering function is changed, the material is aged, and the concrete strength level is lower than the design value. in.
From here we can clearly understand the carbon fiber material in the structural reinforcement of the important role in the future the material may have a wider range of applications.
