Abstract

A method of preparing a woven fabric material (12) for use in a ceramic matrix composite includes passing a desized woven fabric tape (12) having a first inter-filament spacing through a dispersal module configured to transform the desized woven fabric tape (12) into a dispersed woven fabric tape (12) having a second inter-filament spacing greater than the first inter-filament spacing. The dispersal module includes a first charging element (14) with a charged surface and disposed to apply an electric charge to the desized woven fabric tape (12). The method further includes applying a polymer binder to the dispersed woven fabric tape (12) to create a stabilized woven fabric tape (12) having the second inter-filament spacing.
