Carbon fiber is promising for application in the construction industry

Carbon fiber composite material is a new type of material developed with the military industry and belongs to high-tech products. Carbon fiber composites have a series of excellent properties: high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, low electrical conductivity, small heat transfer coefficient, and small thermal expansion coefficient. The carbon fiber composite material can be used as a structural material to carry the load, and can also function as a functional material. In recent years, carbon fiber composite materials have developed rapidly and have been widely used in various applications. Fiber-reinforced plastics include carbon fibers, aramid fibers, and glass fibers. These composite materials are generally characterized by corrosion resistance, UV resistance, light weight, high strength, and non-magnetic properties. In the early 1980s, they were used as engineering materials in their physical and mechanical properties. Breakthrough improvement and improvement. Carbon fiber materials stand out due to their superior performance over other composite materials. Initially, the application of carbon fiber composite materials was confined to aerospace, military, and marine engineering applications. Later, the scope of application was gradually extended to civil engineering. Since the late 1980s to the early 1990s, the reinforcement of concrete structures was a rise in developed countries such as Europe, America, and Japan. This new technology has become a hot topic in the field of civil engineering.

At present, five major applications of carbon fiber composite materials in the construction industry include: carbon fiber reinforced concrete, carbon fiber composite material bar, carbon fiber reinforced adhesive laminate, carbon fiber composite material sheet, and other applications (non-load bearing wall panels, waterproof roof coatings , electromagnetic shielding plates and conductive plates, walls and anti-corrosion coating, wear-resistant flooring materials, chemical resistance floor). The application of carbon fiber composites in civil construction is still a relatively new technology. In the past, due to the high cost and low output of carbon fiber composite materials, their application fields were mainly limited to aerospace, and there were certain difficulties in applications in other applications. In recent years, the application of carbon fiber composite materials has become more and more widespread, with the cost of carbon fiber composite materials increasing. Compared with traditional materials in the construction field (iron and steel, concrete, etc.), carbon fiber composite materials have relatively high prices, but when viewed together, considering the construction cost, use cost, and maintenance cost, the price of carbon fiber composite materials is close to that of traditional building materials. Now. In terms of corrosion resistance, weight, mechanical properties, etc., carbon fiber composite materials have more advantages. In the future, carbon fiber composite materials will have a broad market prospect in the construction industry.
