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 various aspects of chemical corrosion protection and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.
FRP has good electrical properties. 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 radar randoms.
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 transient 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.
