Carbon fiber carbon board has high tensile strength, and it can be used to strengthen the bridge to fully utilize the advantages of carbon fiber carbon board, such as corrosion resistance and anti-aging properties. However, in practical engineering applications, there may be high temperature environments in some areas where the bridge is strengthened. For example, in the desert area, there may be short-term extreme high temperature conditions in the case of sun exposure. Then, at higher pre-stress levels, whether the carbon fiber carbon board will be not tightly clamped or has a large stress loss under high temperature environment or not.
Studies have shown that at normal temperature of 30 ° C, the pre-stressed loss of carbon fiber carbon plate is about 3kN, while carbon fiber carbon plate even if it is at 85 ° C for 4 days, the pre-stress of carbon fiber carbon plate is less than 3%. Compared with eccentricity and installation error, it is basically negligible in engineering applications. Therefore, the carbon fiber carbon board can be normally used even in the summer high temperature, and the construction can be carried out normally in the summer, and the construction time can be shortened, and it is a material suitable for reinforcement repair in a high temperature area.
The provisions on the long-term use of ambient temperature not higher than 60 °C in the Technical Specification for Carbon Fiber Sheet Reinforcement and Restoration of Concrete Structures prove to be slightly conservative, and carbon fiber carbon sheets have the feasibility of being applied to higher temperature environments.
The carbon fiber carbon board produced by Nanjing Mankate Technology Co., Ltd. adopts imported carbon wire and is resistant to humidity and heat aging for 50 years. It not only has high strength and high toughness, but also can be applied to engineering projects under high temperature environment.
