Abstract
A method of manufacturing a composite material in which a fibre matt is placed adjacent a plate electrode in ceramic sol. The application of an electric field to the sol via the electrode results in the deposition of sol particles on the electrode which subsequently permeate the fibre matt. The permeated fibre matt is then removed from the sol, dried out and heated to sinter the sol particles.
