Abstract
A method is disclosed for depositing finely divided solid additive upon surfaces of carbon cloth layer components of a carbonaceous article. The method comprises placing a layer of carbon cloth on a support, beneath a dispersion chamber, dispersing the powdered particulate additive within the chamber by blowing with a stream of gas (preferably nitrogen); allowing the additive to settle; and repeating this routine until the desired thickness of carbon cloth layers and powder is accumulated.
