, paper and other composite materials. High-performance carbon fiber is also the most important reinforcement for the manufacture of advanced composites.
2. Civil construction Carbon fiber cloth
is also used in the reinforcement and reinforcement of industrial and civil buildings, railway highway bridges, tunnels, chimneys, tower structures, etc. In railway buildings, large-scale roof systems and sound insulation walls will have good applications in the future. It is a promising application of carbon fiber. It has the characteristics of low density, high strength, good durability, strong corrosion resistance, chemical corrosion resistance such as acid and alkali, good flexibility and strong strain capacity. The truss-girder roof made of carbon fiber tubes is about 50% lighter than steel, making large-scale structures practical, and the construction efficiency and seismic performance have been greatly improved. In addition, when carbon fiber is used as a reinforced concrete structure, there is no need to add bolts and rivets to fix it. Compared with chopped fiber for concrete
, the disturbance to the original concrete structure is less, and the construction process is simple.
