Glass fiber reinforced plastic (formerly known as glass fiber or fiberglass in English) is an inorganic nonmetallic material with excellent performance, which has many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. It is made from glass balls or waste glass by high-temperature melting, wire drawing, yarn winding, weaving and other processes. The diameter of its monofilaments ranges from several microns to more than 20 meters microns, which is equivalent to 1/20-1/5 of a human hair. Each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments. Glass fiber is usually used as reinforcing material, electrical insulation material, thermal insulation material, circuit board and other fields of national economy in composite materials. Circuit boards and other fields of national economy.
Glass fiber is the skeleton of glass fiber reinforced plastic grating, which plays a load-bearing role in function. Therefore, generally, the layers of glass fiber can be seen from the side wall of glass fiber reinforced plastic grating. Therefore, the number of fiber layers of FRP grating plays a crucial role. Therefore, the number of fiber layers of FRP grating plays a crucial role.
