Method of making a ceramic matrix composite utilizing partially stabilized fibers

A green body ceramic matrix composite material is formed using ceramic fibers in an intermediate state disposed in a green body ceramic matrix material. The fibers may be in either a dry but unfired (green) condition or in a partially fired condition. Selective control of the degree of pre-firing (pre-shrinkage) of the fibers may be used to control the level of residual stresses within the resulting refractory material resulting from differential shrinkage of the fibers and the matrix material during processing of the composite material.
