With the development of society, unsaturated polyester resin, a commonly used thermosetting resin, has become a common material used to manufacture FRP nowadays due to its excellent process performance, chemical performance, and structural performance. Compared with traditional resin casting, FRP based on unsaturated polyester resin has the following advantages.

1. Light weight and high strength.

Unsaturated polyester resin-based FRP density of 1.4 ~ 2.2g/cm³, 4 ~ 5 times lighter than steel, but the strength is not small than the strength of steel, hard aluminum, and cedar wood. This is important for aviation, aerospace, rockets, missiles, artillery, transportation and other products that require weight reduction. For example, the main structure of the Boeing 747 passenger aircraft used glass steel components that reached 2.2 tons, effectively saving aircraft fuel, increasing the speed, extending the duration, and increasing the load.

2. Good corrosion resistance.

FRP based on the unsaturated polyester resin is a good corrosion-resistant material, which can withstand general concentrations of acids, alkalis, and salts. Most organic solvents, seawater, atmosphere, and oil strongly resist microorganisms. It is widely used in petroleum, chemical, pesticide, pharmaceutical, dye, electroplating, electrolysis, smelting, light industry, and other national economic fields, playing a role that other materials cannot replace.

3. Excellent electrical performance.

Glass fiber-reinforced plastic based on unsaturated polyester resin has excellent insulating and dielectric properties at high frequencies. It does not reflect radio waves and is not affected by electromagnetic. It has good microwave magnetic permeability. It is an ideal material for manufacturing radomes. It is used to make insulating parts of instruments, motors, and electrical products, which can improve the service life and reliability of electrical appliances.

4. Unique thermal properties.

The thermal conductivity of FRP based on the unsaturated polyester resin is 0.3 ~ 0.4kcal/mh℃, which is only 1 / 100 ~ 1 / 1000 of metal. It is an excellent thermal insulation material. FRP windows and doors are the fifth generations of new energy-saving building materials. In addition, the linear expansion coefficient of FRP is also very small, close to that of general metal materials. Therefore, the connection between FRP and metal will not cause thermal expansion and generate stress, which benefits its bonding with the metal substrate or concrete structure.

5. Excellent processing performance.

FRP with unsaturated polyester resin as the base material has excellent process performance and simple process. It can be formed at one time. It can be formed at room temperature and atmospheric pressure or cured by heating and pressure. And there are no low molecular by-products in the curing process, so that it can produce relatively uniform products. Due to its excellent process performance has been widely used in recent years to make crafts, imitation marble products, polyester coatings, and other non-glass fiber-reinforced materials.

6. Good design ability.

(1) Functional design. Choose the right UPR and glass fiber, which can be made into a variety of special features of FRP products, such as corrosion-resistant products; can be made into instantaneous high-temperature resistant products; can be made into transparent panels; can be made into fire-resistant, fire-retardant products; it can be made into UV-resistant products;

(2) Structure design. It can design various product structures flexibly, such as FRP doors and windows, FRP grilles, FRP bridges, FRP pipes, FRP water tanks, FRP water tanks, etc.
