摘要： Ultra-high temperature carbide (UHTC) foams and methods of fabricating and using the same are provided. The UHTC foams are produced in a three-step process, including UHTC slurry preparation, freeze-drying, and spark plasma sintering (SPS). The fabrication methods allow for the production of any kind of single- or multi-component UHTC foam, while also providing flexibility in the shape and size of the UHTC foams to produce near-net-shape components.

摘要： A method and device for retaining position of a consumable core during composite article manufacturing is taught herein by inserting a consumable core having a consumable core body and a plurality of retention artifacts into a composite precursor hollow feature of a composite precursor structure. Then positioning the consumable core such that the plurality of retention artifacts projecting from the consumable core exterior surface at least partially engage with a substantially spatially replicate surface geometry in the composite precursor hollow feature. The consumable core is then consumed as a soluble infiltrant to form a composite article.
