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.
