Abstract
A composite fan casing for a gas turbine engine is provided 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 fibers with the braids of reinforcing fibers aligned in a circumferential direction.
Claims15
A composite fan casing for a gas turbine engine, said casing comprising:
- a core having a plurality of core layers of reinforcing fiber bonded together with a thermosetting polymeric resin, each said core layer comprising a plurality of braided reinforcing fibers, said braids of reinforcing fibers aligned in a circumferential direction;
- and
- at least one stiffener bonded to an outer surface of said core.
A method of fabricating a composite fan casing for a gas turbine engine, said method comprises:
- forming a core having a plurality of core layers of reinforcing fiber bonded together with a thermosetting polymeric resin, each core layer comprising a plurality of braided reinforcing fibers formed from tows of fibers, the braids of reinforcing fibers aligned in a circumferential direction;
- and
- bonding at least one stiffener to an outer surface of the core.
