Abstract: Disclosed is a method of coating a high temperature fiber including depositing a base material on the high temperature fiber using atomic layer deposition, depositing an intermediate material precursor on the base material using molecular layer deposition, depositing a top material on the intermediate material precursor or the intermediate layer using atomic layer deposition, and heat treating the intermediate precursor. The intermediate material in the final coating includes a structural defect, has lower density than the top material or a combination thereof. Also disclosed are the coated high temperature fiber and a composite including the high temperature fiber.

Abstract: 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.
