Abstract: A preform for making a casing structure for turbine engines. The preform includes a plurality of reinforcing fiber tows arranged in a two-dimensional weave structure, a three-dimensional weave structure, or a braided structure. The plurality of reinforcing fiber tows include integrally woven or braided fiber tows having a diameter or a density greater than a respective diameter or density of other woven or braided fiber tows in the two-dimensional weave structure, the three-dimensional weave structure, or the braided structure. The integrally woven or braided fiber tows are located in an area of the preform that is bent to form an angled corner to thereby provide strength to a casing structure comprising the angled corner.
