Abstract
A method of infiltrating a fiber structure with a coating and a matrix material includes connecting a wave guide to a fiber structure comprising a plurality of fibers, applying vibration to the fiber structure to separate adjacent fibers at contact points, and depositing a coating on a surface of each of the fibers including contact point surfaces where adjacent fibers have been separated.
Claims18
A method of infiltrating a fiber structure with a coating and a matrix material, the method comprising:
- connecting a wave guide to a fiber structure comprising a plurality of fibers arranged to form a fiber preform of a component or a sheet of fabric;
- wherein the wave guide is selected from the group consisting of a rod inserted into the fiber structure and a plurality of fibers;
- applying vibration to the fiber structure, wherein the vibration separates adjacent fibers at contact points between fibers;
- and
- depositing a coating on a surface of each of the fibers including contact point surfaces where adjacent fibers have been separated.

A method of converting a ceramic fiber structure to a ceramic matrix composite, the method comprising:
- connecting a wave guide to a fiber structure comprising a plurality of fibers arranged to form a fiber preform of a component or a sheet of fabric;
- wherein the wave guide is selected from the group consisting of a rod inserted into the fiber structure and a plurality of fibers woven into the fiber structure;
- applying vibration to the fiber structure, wherein the vibration separates adjacent fibers at contact points between fibers;
- depositing a matrix material to densify the fiber structure.
