Definition of Fiber glass reinforced polymer
Fiber glass reinforced polymer is a composite material that uses glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as a reinforcing material and synthetic resin as a matrix material. The concept of composite material refers to a material that cannot meet the requirements of use, and needs to be combined by two or more materials to form another material that can meet people's requirements, that is, a composite material. For example, although a single glass fiber has high strength, the fibers are loose and can only bear tensile force, but cannot bear bending, shearing and compressive stress, and it is not easy to make a fixed geometric shape, so it is a soft body. If they are bonded together with synthetic resins, they can be made into various hard products with fixed shape, which not only can bear tensile stress, but also can endure bending, compression and shearing stress. This constitutes a glass fiber reinforced plastic matrix composite. Because its strength is equivalent to steel and contains glass components, it also has the same color, shape, corrosion resistance, electrical insulation, heat insulation and other properties as glass.
Characteristics of Fiber glass reinforced polymer
It has stronger impact resistance than ordinary plastics; it is lightweight, mechanically strong, and corrosion-resistant.
Uses of Fiber glass reinforced polymer
As a new type of engineering material, Fiber glass reinforced polymer has broad application prospects from cutting-edge technology to various sectors of the national economy due to its outstanding performance. will become more widespread. During the Second World War, Fiber glass reinforced polymer was mainly used to manufacture various munitions and weapons, such as a small amount of munitions such as radomes and aircraft fuel tanks. After the Second World War, the application of Fiber glass reinforced polymer in the military industry continued to rise, such as military vehicles, boats, bulletproof equipment, aircraft, rockets, missiles, submarines and other military supplies. Many countries (such as Britain, France, Germany, Japan, etc.) have widely used Fiber glass reinforced polymer products in aircraft, missiles, ships, transportation, construction, petrochemical, electrical machinery, etc.
