Electrostatic charge neutralizing fume duct

摘要

A laminated inner wall of a dual wall fume duct for transporting corrosive vapors and gases, and a process for fabricating the wall. The innermost layer of the wall is made of a cured epoxy vinyl ester resin incorporating chopped carbonized carbon fibers. The electrically conductive fibers act to dissipate and neutralize electrostatic charges generated by triboelectric processes.
