Abstract
The present invention relates to a metal matrix composite (MMC). The MMC includes a preform formed from a composition having ceramic particles and ceramic fibers and defining a plurality of voids. The metal matrix composite also includes a support element, such as a metal, disposed within the voids of the preform. The MMC has a wear surface defined by both the preform and the support element.
Claims13
A metal matrix composite comprising:
- a preform comprising ceramic particles and ceramic fibers with said preform having an inner surface and an opposing outer surface and defining a plurality of voids;
- a support element comprising a metal material, said support element having a particular geometry disposed outside of said preform with said geometry formed of said metal material, and said support element disposed within said plurality of voids of said preform between said inner surface and said outer surface of said preform with said metal material of said support element terminating at said inner surface of said preform such that said inner surface of said preform remains exposed;
- and
- a wear surface defined by said exposed inner surface and said support element such that said wear surface is defined by both said preform and said support element.
