1. Lightweight and high strength: The relative density is between 1.5 and 2.0, which is only 1/4 to 1/5 of that of carbon steel, but the tensile strength is close to carbon steel, and even exceeds that of carbon steel, and the specific strength is comparable to that of high-grade alloy steel. compared to. Therefore, it has excellent results in aviation, rockets, space vehicles, high-pressure vessels, and other products that need to reduce their own weight. The tensile, flexural and compressive strengths of some epoxy FRP can reach more than 400Mpa.

2. Corrosion resistance: FRP is a good corrosion-resistant material. Through reasonable selection of raw materials and scientific thickness design, FRP anticorrosion can be used for a long time in acid, alkali, salt, and organic solvent environments, and has good chemical stability. In particular, the corrosion of FRP by water is almost zero, and the corrosion resistance is good. There is no need to use strict internal and external coating or cathodic protection like metal material pipelines, and basically no protection during the service life.

3. Good electrical properties: it is an excellent insulating material, used to make insulators. It can still protect good dielectric properties under high frequency.

4. Good thermal performance: low thermal conductivity, 1.25-1.67kJ/(m.h.K) at room temperature, which is an excellent thermal insulation material. It is an ideal thermal protection and ablation resistant material under transient ultra-high temperature conditions.

Good thermal insulation performance: As the FRP products are composited by polymer materials and reinforced materials, the water body can run at a constant temperature in summer to avoid the breeding of microorganisms.

5. Good designability:

Various structural products can be flexibly designed according to needs to meet the requirements of use, and the products can have a good integrity.

Materials can be fully selected to meet the performance of the product, such as: corrosion resistance, instantaneous high temperature resistance, high strength in a certain direction, and good dielectric properties can be designed.

6. Excellent workmanship:

The molding process can be flexibly selected according to the shape, technical requirements, use and quantity of the product. The process is simple, it can be molded at one time, and the economic effect is outstanding, especially for products with complex shapes and small quantities that are not easy to form. Its process superiority is more prominent.

7. Excellent impact resistance: The strength of glass fiber reinforced plastic is higher than that of steel pipe ductile iron and concrete, and its specific strength is about 3 times that of steel, 10 times that of ductile iron, and 25 times that of concrete; the weight of 1.5kg is not damaged under the impact height of 1600mm. .

8. Compared with other anti-corrosion forms, FRP has low cost and long life.
