Abstract
A ceramic-forming prepreg tape is prepared by (a) dispersing in water a ceramic-forming powder and a fiber, (b) flocculating the dispersion by adding a cationic wet strength resin and an anionic polymer, (c) dewatering the flocculated dispersion to form a sheet, (d) wet pressing and drying the sheet, and (e) coating or impregnating the sheet with an adhesive selected from the group consisting of a polymeric ceramic precursor, and a dispersion of an organic binder and the materials used to form the sheet. The tape can be used to form laminates, which are then fired to consolidate the tapes to a ceramic.
