Abstract: A method of fabricating a carbon fiber-reinforced article includes providing carbon fibers that have surfaces that include an initial interfacial bonding strength capacity with respect to bonding with boron nitride. The surfaces are then modified to reduce the initial interfacial bonding strength capacity. A layer of boron nitride is then deposited on the modified surfaces and the carbon fibers are then embedded in a ceramic matrix. A carbon fiber-reinforced article includes the carbon fibers, the layer of boron nitride on the surfaces of the carbon fibers, and the ceramic matrix. The article exhibits non-brittle fracture.
