Lightweight and high-strength

The relative density is between 1.5 and 2.0, only 1/4 to 1/5 of that of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, while the specific strength can be compared with high-grade alloy steel. Therefore, it has excellent performance in aviation, rockets, spacecraft, high-pressure vessels, and other applications that require weight reduction. The tensile, bending, and compressive strength of some epoxy FRP can reach over 400Mpa.

corrosion preventive

FRP is a good corrosion-resistant material that has good resistance to atmospheric, water, and general concentrations of acids, alkalis, salts, as well as various oils and solvents. It has been applied to various aspects of chemical anti-corrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.

Good electrical performance

It is an excellent insulation material used to manufacture insulators. It can still protect good dielectric properties at high frequencies. The microwave has good transparency and has been widely used in radar antenna covers.

Good thermal performance

FRP has a low thermal conductivity of 1.25~1.67 kJ/(m · h · K) at room temperature, which is only 1/100~1/1000 of that of metals, making it an excellent insulation material. In the case of instantaneous ultra-high temperature, it is an ideal thermal protection and erosion resistant material, which can protect spacecraft from high-speed airflow erosion above 2000 ℃.

Good designability

(1) Various structural products can be flexibly designed according to needs to meet usage requirements and ensure good overall integrity of the product.

(2) Materials can be fully selected to meet the performance requirements of the product, such as designing products that are corrosion-resistant, resistant to instantaneous high temperatures, have particularly high strength in a certain direction, have good dielectric properties, and so on.

Excellent craftsmanship

(1) The molding process can be flexibly selected based on the shape, technical requirements, purpose, and quantity of the product.

(2) The process is simple and can be molded in one go, with outstanding economic effects, especially for products with complex shapes and small quantities that are difficult to shape, highlighting its technological superiority.
