Carbon fiber has many excellent properties. Carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, super high temperature resistance and good fatigue resistance under non oxidizing environment. The specific heat and conductivity are between non metal and metal. The thermal expansion coefficient is small and has anisotropy, good corrosion resistance and good X ray transmission. Good conductive and thermal conductivity, good electromagnetic shielding and so on.
The long-span cable bridge is assembled by extruded FRP profiles, which is suitable for power cables, control cables, lighting cables and accessories.
Compared with the iron bridge, it has long service life (general design life of twenty years), convenient installation and low cost (the proportion is only 1/4 of carbon steel, no fire in the construction, the length of the single bridge can reach 8 meters, even longer), the cutting is convenient, and the maintenance is not necessary.
