Generally speaking, construction projects have a long service life, and some projects have legacy problems caused by low design load standards. At the same time, most construction projects are exposed to the external environment, and aging is inevitable due to environmental erosion. When repairing the building structure, carbon fiber unidirectional cloth is often used to stick to the surface of the concrete structure, so as to realize the reinforcement and reinforcement of the concrete structure.

Carbon fiber is known as "black gold" internationally. It not only has the inherent characteristics of carbon materials, but also has the softness of textile fibers. Carbon fiber needs to go through many processes such as pre-oxidation, high-temperature carbonization, graphitization, and surface treatment from raw silk to finished product. One of the advantages of carbon fiber is its light weight. The most intuitive change brought about by the application of this material in a car is the reduction in the mass of the entire vehicle. On the premise that the power system remains unchanged, the weight-reduced body will bring a better acceleration experience. Compared with throwing away the air conditioner, audio and other configurations, the weight loss method.

With the maturity of carbon fiber and composite material technology, people's research has been in-depth, and the application of carbon fiber and composite material in the photovoltaic industry will be more and more.
