BORON NITRIDE COATED FIBER AND COMPOSITE ARTICLE COMPRISING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a ceramic matrix composite incorporating boron nitride coated reinforcing fiber therein.

SOLUTION: The boron nitride coated fiber and the composite article comprising the fiber are described. The fiber can be desized and coated in one continuous process without requiring purging in between processing steps. The fiber may be heated up in an ammonia atmosphere and may then be brought into contact with a reaction mixture comprising a boron feed source and a nitrogen feed source. Once coated, the fiber may be used in the ceramic matrix composite.
