Product Introduction:
The main reason why carbon fiber has electromagnetic shielding ability is because of its good electrical conductivity. The common volume resistivity of carbon fiber is between (0.8~1.8)×10-3Ω·cm, and the conductivity will increase with the increase of heat treatment temperature. Therefore, after high temperature graphitization treatment, carbon fiber can become an excellent reflective material for electromagnetic waves.
In addition to excellent electromagnetic shielding performance, carbon fiber also has the characteristics of high strength and light weight. In foreign countries, carbon fiber composite materials have been applied to stealth aircraft and other aircraft, and the carbon fiber has been modified to reduce electromagnetic wave reflection.
The smart car key will emit a radio frequency signal. Put the car key in a signal shielding bag for safekeeping. By adding a shielding layer to the key, the signal of the smart car key can be effectively prevented from being copied and stolen.
