Abstract
A method of fabricating a fibrous ceramic preform includes forming a plurality of coated ceramic tows by introducing a polymeric composition to each of a plurality of ceramic tows, and dispersing and stabilizing each of the plurality of ceramic tows such that a coating of a first polymer binder forms on individual filaments of respective ones of the plurality of ceramic tows, incorporating the plurality of coated ceramic tows into a ceramic fabric, applying a tackifier composition comprising a second polymer binder and a second solvent to the ceramic fabric, and incorporating the ceramic fabric into the preform. The first polymer binder is insoluble in the second solvent.
