摘要： A composite fan casing for a gas turbine engine includes, in an exemplary embodiment, a core having a plurality of core layers of reinforcing fiber bonded together with a thermosetting polymeric resin. Each core layer includes a plurality of braided reinforcing fiber tows. The braids of reinforcing fiber tows are aligned in a circumferential direction with each fiber tow including a plurality of reinforcing fibers. The core also includes at least one additional fiber tow braided into at least one predetermined axial location to form at least one concentrated stiffening ring.
