摘要： Disclosed is a method of making high temperature fiber including chemically bonding high temperature material to a fiber template at a first temperature to form a precursor fiber and processing the precursor fiber at a second temperature to form the high temperature fiber. The first temperature does not equal the second temperature. Also disclosed are high temperature fibers made by the method.

摘要： A fabrication apparatus for fabricating ceramic structures of controlled size and composition is provided. The fabrication apparatus includes an additive manufacturing machine configured to dispense preceramic materials in a printed pattern, the printed pattern corresponding to the ceramic structures of the controlled size and composition, a radiation emitter configured to emit curing radiation toward the printed pattern to cure the preceramic materials and a lamp element configured to shine light on the preceramic materials to convert the preceramic materials to ceramics.

摘要： Disclosed is a modified preceramic polymer having a polymer backbone consisting of silicon or a combination of silicon and carbon; and a pendant modifier bonded to the backbone wherein the modifier includes silicon, boron, aluminum, a transition metal, a refractory metal, or a combination thereof. The modified preceramic polymer can be used to form a ceramic matrix composite.
