Claims17
An article comprising:
- a gas turbine engine fan casing having a circumference and oppositely-disposed axial ends;
- and
- at least one interposed mounting flange operably connected to the fan casing about the circumference thereof and between the axial ends of the fan casing, wherein the mounting flange comprises at least one circumferentially oriented core fiber that circumscribes the fan casing.
An article comprising:
- a gas turbine engine fan casing having an outer circumference and oppositely-disposed axial ends;
- at least one interposed mounting flange on the outer circumference of the fan casing between the axial ends thereof, the mounting flange comprising:
- at least one circumferentially oriented core fiber that circumscribes the fan casing;
- and
- at least one layer of attachment fibers operably connecting the core fiber to the fan casing about the circumference and wherein the mounting flange comprises a material selected from the group consisting of glass fibers, graphite fibers, carbon fibers, ceramic fibers, aromatic polyamide fibers, and combinations thereof.
