Carbon fiber is a new type of high-performance fiber reinforced material with high strength, high modulus, high temperature resistance, wear resistance, fatigue resistance, corrosion resistance, creep resistance, electrical and thermal conductivity and many other excellent properties. It can reduce the weight of the component, thereby improving the technical performance of the component. Therefore, the use of carbon fiber as an electric heating body has many excellent properties that metal, PTC and other electric heating bodies cannot match:
1. Rapid heating
It can produce far infrared rays of 8μm-15μm, the light of life needed by the human body.
2. High electric heating conversion efficiency, saving electric energy
Carbon fiber electric heating element is an all-black body material, the electric heating conversion efficiency is 30% higher than that of metal heating, and the electric heating efficiency is about 100%.
3. High tensile strength
Under the same allowable current load area, the strength of carbon fiber is 6-10 times higher than that of metal wire, and it will not break during use, so the tensile strength does not change during the electric heating process.
4. No arc when disconnected
Effectively prevent the occurrence of fire.
5. Lightweight
Effectively reduce the weight of the component, thereby improving the technical performance of the component.
6. Stable chemical properties
Corrosion resistant and not easily oxidized. When heated to 3000 degrees in an oxygen-free state, its mechanical properties will not change. In the electric heating state, it overcomes the shortcomings of low strength of metal wire, PTC, and silicon carbide electric heating bodies and easy oxidation and burnout.
7. Long service life
The carbon fiber heating element has the same life span as the building.
