1. Lightweight and high strength
The relative density is between 1.5-2.0, which is only 1/4~1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared with high-grade alloy steel. Therefore, it has remarkable results in aviation, rockets, Yumu aircraft, high-pressure containers and other product applications that require weight reduction. The tensile, flexural and compressive strengths of some cyclochloro-FRPs can reach more than 400Mpa.
2. Preservative
FRP is a good corrosion-resistant material, and has good resistance to the atmosphere, water and general concentrations of acids, alkalis, salts, and various 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, etc.
3. Electron
It is an excellent insulating material and is used to make insulators. It still protects good dielectric properties at high frequencies. It has good microwave permeability and has been widely used in radar antenna devices.
4. Good thermal performance
FRP has low thermal conductivity, 1.25-1.67kJ/(m-h-K) at room temperature, only 1/100-1/1000 of metal, and is an excellent thermal insulation material. In the case of instantaneous ultra-high temperature, it is an ideal thermal protection and ablation resistant material, which can protect the spacecraft at temperatures above 2000°C
Withstand the erosion of high-speed airflow.
5. Good designability
(1) Various structural products can be flexibly designed according to needs to meet the requirements of use, which can make the product have a good integrity.
(2) can fully select materials to meet the performance of the product, such as: can design corrosion resistance, instantaneous high temperature resistance, the product has special high strength in a certain direction, good dielectric properties, and so on.
6. Excellent craftsmanship
(1) The molding process can be flexibly selected according to the shape of the product, technical requirements, use and quantity.
(2) The process is simple, it can be formed at one time, and the economic effect is outstanding, especially for products with complex shapes and a small number of products that are not easy to form, it highlights its technological superiority.
