Ceramic matrix composites and method of making

A method for manufacturing a ceramic matrix composite comprising:

• placing in an infiltration chamber a laminate comprising:
• a plurality of layers that comprise fibers;
• wherein each layer comprises a plurality of fill fibers and a plurality of warp fibers;
• wherein the plurality of layers includes a first layer, a second layer and a third, wherein the first layer is an outermost layer of the laminate, the second layer is in an interior of the laminate closer to a center of the laminate than the first layer, and the third layer is in the interior of the laminate closer to the center of the laminate than the second layer, wherein a spacing between weft fibers of the first layer is greater than the spacing between weft fibers of the second layer and the spacing between warp fibers of the first layer is the same as the spacing between warp fibers of the second layer, and wherein a spacing between weft fibers of the second layer is greater than the spacing between weft fibers of the third layer and the spacing between warp fibers of the second layer is the same as the spacing between warp fibers of third layer;
• infiltrating the plurality of layers with a precursor that comprises a ceramic precursor;
• and
• joining a plurality of laminates such that a fiber concentration gradient per unit volume in each laminate is different from that of another laminate in the plurality of laminates.
