METHODS OF FORMING CERAMIC MATRIX COMPOSITE STRUCTURES, APPARATUSES FOR FORMING CERAMIC MATRIX COMPOSITE STRUCTURES, AND CERAMIC MATRIX COMPOSITE STRUCTURES

摘要

A method of forming a ceramic matrix composite structure. The method comprises forming at least one prepregged composite material comprising a ceramic fiber preform and a pre-ceramic matrix slurry. The ceramic fiber preform may comprise a single tow of ceramic fibers, a tape of multiple tows or a woven fabric. The at least one prepregged composite material is placed over at least one surface of a tool using an advanced fiber placement apparatus to form an at least partially uncured composite material structure. The at least partially uncured composite material structure is exposed at least to elevated temperatures to convert the at least partially uncured composite material structure into a ceramic matrix composite structure. A system for forming a ceramic matrix composite structure, an advanced fiber placement apparatus, and a ceramic matrix composite structure are also described. The ceramic matrix can be both an oxide and non-oxide.
