1. Light weight and high strength;
The relative density is between 1.5 ~ 2.0, which is only 1 / 4 ~ 1 / 5 of that of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, and the specific strength can be compared with that of high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, spacecraft, high-pressure vessels and other products that need to reduce self weight. The tensile, bending and compressive strength of some epoxy FRP can reach more than 400MPa. Density, strength and specific strength of some materials.
2. Good corrosion resistance
FRP is a good corrosion-resistant material, which has good resistance to atmosphere, water, general concentration of acid, alkali, salt, as well as a variety of oils and solvents. It has been applied to all aspects of chemical anti-corrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals and so on.
3. Good electrical performance
It is an excellent insulating material used to make insulators. It can still protect good dielectric at high frequency. With good microwave transmission, it has been widely used in radar radome.
4. Good thermal performance
FRP has low thermal conductivity, which is 1.25 ~ 1.67kj / (m · h · K) at room temperature, only 1 / 100 ~ 1 / 1000 of metal. It is an excellent thermal insulation material. Under the condition of instantaneous ultra-high temperature, it is an ideal thermal protection and ablation resistant material, which can protect the spacecraft from the scouring of high-speed airflow above 2000 ℃.
5. Good designability
a. Various structural products can be flexibly designed according to the needs to meet the use requirements, which can make the products have good integrity.
b. Materials can be fully selected to meet the performance of products, such as corrosion-resistant, instantaneous high temperature resistant, products with special high strength in a certain direction, good dielectric, etc.
c. Excellent workmanship.
d. The molding process can be flexibly selected according to the shape, technical requirements, purpose and quantity of products.
e. The process is simple, it can be formed at one time, and the economic effect is outstanding. Especially for the products with complex shape and small quantity that are not easy to form, its superior process is more prominent.
