1. Lightweight, high strength, good mechanical properties. Mechanical properties are very important properties of materials. FRP has the advantages of high specific strength, large specific modulus, fatigue resistance and shock absorption performance. The density of FRP is usually 1.6-2.0t/m3, which is only /5-1/4 that of steel, about 1/3 lighter than metal aluminum, and its mechanical strength can reach or even exceed the strength of ordinary carbon steel.
2. Flexible forming process and strong designability. FRP pultruded profiles can make full use of the characteristics of its performance directionality, structural performance designability, and the overall molding of large components to achieve comprehensive optimization of efficiency, performance, function and cost, and meet the requirements of practical applications.
3. Excellent chemical resistance and easy maintenance. The electrochemical corrosion mechanism of FRP and ordinary metals is different. The surface resistance value of its products is 1×1016~1×1022. There will be no ions dissolved in the electrolyte solution, so it is resistant to the atmosphere, water and general concentrations of acids, alkalis and salts. Other media have good chemical stability, strong resistance to corrosion, and no anti-corrosion treatment is required.
4. Long service life and low life cycle cost. The service life of FRP can reach 30~50 years, which is 2~3 times that of steel and 5~10 times that of cast iron materials. Calculated based on the average service life of the mine 35 years, within the service life of the mine, the use of FRP pultruded profiles can be Realize an investment.
