Abstract
A method for making a fiber-reinforced ceramic matrix composite article is disclosed wherein a ceramic matrix material in the form of a glass powder is combined with a fibrous reinforcing material such as a fiber tow, and the powder and tow are transported into a hot zone wherein they are consolidated together by winding under tension onto a collection mandrel at a temperature above the annealing temperature of the glass. High density composites are provided without the use of subsequent high pressure consolidation treatments.
