Lightweight and strong
The relative density is between 1.5 and 2.0, only 1/4~1/5 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 high-grade alloy steel. As a result, it has achieved excellent results in aerospace, rockets, spacecraft, high-pressure vessels, and other applications that require weight reduction. Some epoxy FRPs have tensile, bending and compressive strengths of more than 400 MPa.
Good corrosion resistance
FRP is a good corrosion-resistant material with good resistance to atmospheric, water and general concentrations of acids, bases, salts and a variety of oils and solvents. It has been applied to all aspects of chemical corrosion protection and is replacing carbon steel, stainless steel, wood, non-ferrous metals and so on.
Good electrical performance
It is an excellent insulating material used to make insulators. Good dielectric properties are still protected at high frequencies. It has good microwave permeability and has been widely used in radomes.
Good thermal performance
FRP has a low thermal conductivity, which is 1.25~1.67kJ/(m·h·K) at room temperature, and only 1/100~1/1000 of metal. It 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 from high-speed airflow at 2000 °C.
Good design
(1) Various structural products can be flexibly designed according to needs to meet the requirements of use, and the products can be well integrated.
(2) The material can be fully selected to meet the performance of the product, such as: can be designed to resist corrosion, resistant to transient high temperature, the product has a particularly high strength in a certain direction, good dielectric properties, and so on.
Excellent craftsmanship
(1) The molding process can be flexibly selected according to the shape, technical requirements, use and quantity of the product.
(2) The process is simple, it can be molded at one time, and the economic effect is outstanding, especially for products with a complicated shape and less forming, and the process superiority is more prominent.
