As a new star in the reinforcement and repair, carbon fiber cloth has attracted much attention since its production. The market's understanding of this new type of reinforcing and repairing material is not very sufficient, which has led to the uneven quality of carbon fiber cloth materials in the market. As a construction company, of course, we hope to be able to buy high quality products. In addition to the self-promotion of the business, the samples are sent to the test, and the quality of the materials can be distinguished by comparing the key indicators. Today, we will talk about the key data.
According to the relevant requirements of the national GB50728 "Technical Specifications for Safety Evaluation of Engineering Reinforcement Materials". the first indicator of carbon fiber cloth is the standard value of tensile strength. The required value should be greater than or equal to 3400 MPa. And the second is the tensile modulus of elasticity. The required value should be greater than or equal to 2.3*10, the fifth power MPa. The third is elongation ratio which should be greater than or equal to 1.6%. The fourth is the bending strength and the interlaminar shear strength, which are respectively greater than or equal to 700 MPa and 45 MPa. The fifth is the tensile bond strength of the fiber composite and the substrate. For concrete and masonry, the substrate should be greater than or equal to 2.5 MPa and is a cohesive failure of the substrate. The last indicator is the mass per unit area, which is less than or equal to 300g per square.
