A fabric for providing reinforcement and the like which is made from a two dimensional flat fabric which includes portions that the warp and weft fibers are interlocked together and portions that are non-interlocked together that allow the fabric to be folded to create a three dimensional structure without the need for cutting and darting.

Reinforced article and method of making

A ceramic matrix composite part having elongated cooling channels within the wall thereof is manufactured by inserting decomposable inserts within a woven ceramic fiber preform. The inserts are tows of continuous carbon fibers surrounded by a carbonaceous filler, and are inserted where the channels are desired. The preform, with the inserts in place, is disposed within a mold. A ceramic matrix material is added and the fiber preform is consolidated with the ceramic matrix material. The consolidated part is then heated to thermally decompose the inserts to create the elongated channels within the part. The inserts may be flexible and woven into the preform using an automated weaving loom, or they may have limited flexibility and be inserted by machine or by hand.
