Abstract
A method of preparing a fibrous preform for use in a ceramic matrix composite comprises coiling a serving yarn around a ceramic tow to form a served tow, the serving yarn comprising a polymer material with embedded ceramic particles, incorporating the served tow into a woven fabric, the woven fabric comprising a plurality of served tows, and removing the polymer material of the serving yarn such that the embedded ceramic particles remain in the woven fabric.
