Abstract
A CMC sandwich used to fabricate CMC structures includes facesheets bonded to a core reinforced with a ceramic truss comprising an array of CMC pins. The binder matrix in the ends of the pins is removed, leaving exposed, flexible ceramic fibers. The exposed ceramic fibers are bent so as to extend parallel to the facesheets, and are bonded to one or more plies of the facesheets. The binder matrix in the ends of the ceramic pins may be removed by mechanical or chemical processes.
