METHOD FOR DEBUNDLING AND DISPERSING CARBON FIBER FILAMENTS UNIFORMLY THROUGHOUT CARBON COMPOSITE COMPACTS BEFORE DENSIFICATION

摘要

A method of forming a carbon fiber reinforced carbon composite articles includes the steps of: (a) selecting carbon fiber bundles that have a sizing material that is soluble in a selected dispersing fluid; (b) mixing the selected carbon bundles and other blend components in a dispersing fluid so as to debundle the carbon fibers and to produce a slurry of blend components in which the individual carbon fibers are substantially randomly oriented and uniformly distributed throughout; and (c) removing the dispersing fluid either prior to or during the process of forming of the solids of the slurry into a carbon fiber reinforced carbon composite article having individual carbon fibers substantially randomly oriented and uniformly distributed throughout.
