Abstract
A method of manufacturing a composite material which comprises ceramic fibers in a matrix of a ceramic material. A woven mat of ceramic fibers having an electrically conductive coating thereon is immersed in a sol. The sol comprises surface-charged ceramic particles. A potential difference is applied between the fibers and a second electrode placed in the sol. The applied potential difference is continued until the mat is permeated by the ceramic particles in the sol. The mat is removed from the sol and is then heated to sinter the permeated ceramic particles.
