What material compositions are common for flexible static dischargers?

Flexible static dischargers are designed to safely dissipate static electricity from the aircraft to prevent electrical buildup, which can lead to sparking or other electrical issues. The correct choice, which includes silver or carbon impregnated braid, is ideal for this purpose due to the excellent conductive properties of silver and the durability of carbon materials.

Silver is one of the best conductors of electricity, which enhances the efficiency of the discharger in allowing static charge to flow away from the aircraft. Carbon, when impregnated in the braid, offers good conductive properties while also being lightweight and resistant to environmental wear. This composition allows the static discharger to perform effectively under various conditions while ensuring longevity and reliability.

Other materials listed, such as copper and rubber, aluminum and plastic, or steel and fiberglass, do not provide the same levels of conductivity, durability, and overall effectiveness required in aviation applications for static discharging. Therefore, the unique properties of silver or carbon impregnated braid make it the preferred choice for flexible static dischargers in aircraft systems.
