Abstract

A method for making a ceramic matrix composite article wherein a dispersion of a ceramic matrix powder in a wax-containing thermoplastic vehicle is applied to an inorganic fiber reinforcement material to form a prepreg material such as a prepreg tow, and the tow is collected and formed into a preform for the article which is then subjected to binder burnout and consolidation, wherein the prepreg material is heated to a temperature sufficient to evaporate at least about 50% by weight of the wax component therefrom prior to the collection and forming of the material into the preform.
