A ceramic matrix composite structure (10) includes a load carrying fluted core (16) formed from a ceramic matrix composite. The fluted core (16) includes a plurality of nested flute members (18a, b) laminated between a pair of ceramic matrix composite facesheets (12, 14). The flute members (18a, b) are fabricated by wrapping ceramic resin fabric around a mandrel, curing the flute members (18a, b) and then removing the mandrels. The structure may include reinforced areas in which the facesheets (12, 14) are laminated directly together to receive fasteners for mounting the structure. The structure may include both flat and curved portions (Fig. 2).
摘要:
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.

A CMC sandwich used to fabricate CMC structures includes facesheets (24,26) bonded to a core (22) reinforced with a ceramic truss (25) comprising an array of CMC pins (28). 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.
