The fiberglass fan is good or bad in the following aspects:
1. Strong relative density
The relative density is between 1.5 and 2.0, only 1/4 to 1/5 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 to alloy steel. Therefore, it has been effective in the application of rockets, spacecraft, high-pressure containers, and other products that require weight reduction. The tensile, flexural, and compressive strength of some epoxy FRP can reach above 400 Mpa. The density, strength, and specific strength of some materials.
2. Good corrosion resistance.
FRP is a good corrosion resistant material that has good resistance to atmospheric, water, and general concentrations of acids, bases, 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, nonferrous metals, etc.
3. Good electrical performance
It is an excellent insulating material used to manufacture insulators. It can still protect good dielectric properties at high frequencies.
4. Good thermal performance
FRP has a low thermal conductivity, ranging from 1.25 to 1.67 kJ/(m · h · K) at room temperature, only 1/100 to 1/1000 of metal, making it an excellent thermal insulation material. It is an ideal thermal protection and ablation resistant material under transient ultra-high temperatures, and can protect spacecraft from high-speed airflow at temperatures above 2000 ℃. The relative density is between 1.5 and 2.0, only 1/4 to 1/5 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 to alloy steel. Therefore, it has been effective in the application of rockets, spacecraft, high-pressure containers, and other products that require weight reduction. The tensile, flexural, and compressive strength of some epoxy FRP can reach above 400 Mpa
The quality of fiberglass fans is as follows:
1. Strong relative density
The relative density ranges from 1.5 to 2.0, which is only 1/4 to 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 to alloy steel. Therefore, it has been effective in the application of rockets, spacecraft, high-pressure vessels, and other products that require weight reduction. The tensile, bending, and compressive strength of some epoxy FRP can all reach over 400Mpa. The density, strength, and specific strength of some materials.
2. Good corrosion resistance.
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.
3. Good electrical performance
It is an excellent insulation material used to manufacture insulators. It can still protect good dielectric properties at high frequencies.
4. Good thermal performance
FRP has a low thermal conductivity, ranging from 1.25 to 1.67kJ/(m · h · K) at room temperature, only 1/100 to 1/1000 of metal, making it an excellent insulation material. Under instantaneous ultra-high temperature conditions, it is an ideal thermal protection and ablation resistant material that can protect spacecraft from high-speed airflow erosion above 2000 ℃. The relative density ranges from 1.5 to 2.0, which is only 1/4 to 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 to alloy steel. Therefore, it has been effective in the application of rockets, spacecraft, high-pressure vessels, and other products that require weight reduction. The tensile, bending, and compressive strength of some epoxy FRP can all reach over 400Mpa.
