Abstract: Methods of making ceramic matrix prepregs are described. The methods include exposing a coated tow of ceramic fibers to a ceramic matrix slurry comprising a solvent and ceramic precursor. The coating is at least partially removed and the slurry infuses into the ceramic fibers to form prepreg. Steps to form ceramic matrix composites are also described, including forming the prepreg into a green body, and sintering the ceramic precursor.

One method includes a) providing a photopolymerizable composition; b) selectively curing the photopolymerizable composition using actinic radiation to form an article in the shape of an orthodontic article having a plurality of layers of at least one photopolymerized polymer; and c) exposing the article to water by submersion in water, thereby hydrating the article. A sheet of the at least one photopolymerized polymer has a bending modulus when hydrated of 100 MPa or greater and 2200 MPa or less. Another method includes exposing the orthodontic article to water vapor and hermetically sealing the hydrated orthodontic article in a container. Hydrated orthodontic articles are also provided, including an orthodontic article that is prepared according to one of the methods. The present disclosure further provides kits, including an orthodontic article and instructions for exposing the orthodontic article to water to hydrate the orthodontic article, as well as including a hydrated orthodontic article hermetically sealed in a container.
