Abstract
A ceramic body of controlled porosity is formed by coating unidirectional fiber carriers with a hardenable liquid resin bearing powdered ceramic material, which resin is subsequently cured, hardened, or cooled to provide a green body which may be assembled with similar layers, in a desired shape, and subsequently sintered, to form a ceramic body having continuous pores corresponding to the position of the fibers.
