Dry prepregs for ceramic matrix composites are described. The dry prepregs comprise a tow or fabric of ceramic fibers infiltrated with preceramic matrix comprising low levels of an aqueous solvent. The preceramic matrix contains an inorganic portion and a binder system. Binder systems comprising a binder and a plasticizer for the binder are described.

Dry prepreg for ceramic matrix composites

Fiber tows including a heat-activatable sizing are described. The sizing compositions have a first modulus at 25&#xb0; C. of at least 150 megapascals (MPa) and no greater than 400 MPa; and a second modulus of 100,000 pascals (Pa) at a temperature of no greater than 160&#xb0; C. Methods of preparing articles from such sized fiber tows and the articles comprising such sized fiber tows, including unidirectional and bidirectional constructions are also described.

Fiber tows with a heat-activated sizing

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.

Method of making ceramic matrix slurry infused ceramic tows and ceramic matrix composites

Described are catalyst compositions, oxidizable-gas burner systems, methods of oxidizing oxidizable gas, and methods of preparing catalyst compositions and oxidizable-gas burner systems.
