Abstract
A method of forming a ceramic matrix composite (CMC) comprises applying a boron nitride (BN) aerogel to a fibrous material to form a pretreated fibrous material, depositing, using chemical vapor infiltration (CVI), a BN interface coating (IFC) on the pretreated fibrous material, and depositing a matrix on the BN IFC and the pretreated fibrous material.
