Abstract
The present invention is an integral composite structural (ICS) material comprising an open metal structure having at least one external side and internal surfaces defining a plurality of open shapes with a ceramic matrix composite bonded to at least one external side and the surfaces of at least a substantial portion of the plurality of open shapes and occupying at least a substantial portion of the plurality of open shapes. The open metal structure, independent of the ceramic matrix composite, has a total metal volume percent in the range of about 10% to about 90%, with no dimension of any open shape being greater than about ¾ inch. The ceramic matrix layer covers a substantial portion of at least one external side of the open metal structure. At least one external side of the metal portion of the ICS material is bonded with a ceramic matrix composite such that the ceramic layer occupies at least a significant portion of the open pores of the metal portion and is bonded to a significant portion of at least one external side of the metal element. The present invention is also a method of manufacturing such an ICS material.
