A fibrous ceramic preform includes a plurality of ceramic fibers, a first amorphous layer, and an interfacial coating layer. The interfacial coating layer includes an anisotropic region adjacent the at least one amorphous layer, and an isotropic region on a side of the anisotropic region opposite the at least one amorphous layer.

Method to form aligned interface coating on silicon carbide fibers

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