FRP bridge is a new type of bridge made of glass fiber as a reinforcing material and composite. Compared with the traditional metal bridge, the FRP bridge has the characteristics of light weight and high strength, and its weight is only about 1 3 of the traditional bridge, and it has higher strength and rigidity.
First of all, the lightweight and high-strength characteristics of FRP bridge benefit from the glass fiber reinforced material it uses. Glass fiber is a high-strength, high-modulus inorganic fiber, with excellent mechanical properties and corrosion resistance. By compounding glass fiber with resin and other materials, FRP materials with high strength and high stiffness can be prepared. This material is not only lightweight, but also has very good fatigue resistance and corrosion resistance, which can be used for a long time under harsh environmental conditions.
Secondly, the FRP bridge also has excellent bearing capacity. Due to its use of glass fiber reinforced material, the cross-sectional size of FRP bridge is much smaller than that of traditional metal bridge under the same bearing conditions, which can effectively save space and materials. At the same time, the span of FRP bridge has also been greatly improved, which can adapt to a variety of different site conditions.
In addition, FRP bridge also has good thermal insulation and thermal insulation properties. Because there are many bubbles and micropores inside, it can effectively insulate the transfer and loss of heat. In winter, the use of FRP bridge can effectively improve the thermal insulation performance of the pipeline and reduce the waste of energy.
To sum up, FRP bridge has the characteristics of light weight and high strength, strong bearing capacity, good thermal insulation and thermal insulation performance, and is an excellent building structure material. It has been widely used in construction, transportation, electric power and other fields. At the same time, due to its excellent performance and long-term service life, FRP bridge has also become a very valuable investment product.
