摘要:
A composite is produced by admixing a matrix-forming material with organic binding material, forming the resulting mixture into a tape, disposing a layer of spaced boron nitride coated filaments between at least two of the tapes to form a layered structure, laminating the layered structure, heating the layered structure to remove organic binding material and hot pressing the resulting porous structure to form a composite containing spaced boron nitride coated filaments.

A composite is produced by depositing a slurry of infiltration-promoting material and organic binding material on a layer of boron nitride coated fibrous material forming a tape therewith on drying, firing the tape to burn out organic binding material and infiltrating the resulting porous body with a solution of boron and silicon.

摘要:
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.
