ABSTRACT:
A composite comprised of a ceramic matrix and a plurality of layers of boron nitride coated fibrous material, said coated fibrous material comprising at least about 10% by volume of said composite, and said matrix having a thermal expansion coefficient which ranges from lower than that of said coated fibrous material to less than about 15% higher than that of said coated fibrous material.
