Tethered flange corners including at least one ply of barrier fibers and at least one fiber tow wrapped about the barrier fibers. Also included are flanges having a tethered corner containing at least one ply of barrier fibers, at least one fiber tow wrapped about the barrier fibers, at least one ply of filler fibers applied over the fiber tow, and at least one ply of flange fibers applied over the filler fibers. Additionally included are articles incorporating a composite structure having a flange with a tethered corner containing at least one ply of barrier fibers and at least one fiber tow wrapped about the barrier fibers.

What is claimed is: 1. A tethered flange corner comprising: at least one ply of barrier fibers comprising a multidirectional fiber preform; and at least one fiber tow wrapped circumferentially about the barrier fibers to produce the tethered flange corner. 2. The tethered flange corner of claim
What is claimed is: 1. A tethered flange corner comprising: at least one ply of barrier fibers comprising a multidirectional fiber preform; and at least one fiber tow wrapped circumferentially about the barrier fibers to produce the tethered flange corner. 2. The tethered flange corner of claim 1 wherein the barrier fibers are comprised of a material selected from the group consisting of glass fibers, graphite fibers, carbon fibers, ceramic fibers, aromatic polyamide fibers, and combinations thereof. 3. The tethered flange corner of claim 1 wherein the fiber tow is comprised of a material selected from the group consisting of glass fibers, graphite fibers, carbon fibers, ceramic fibers, aromatic polyamide fibers, and combinations thereof. 4. The tethered flange corner of claim 1 wherein the barrier fibers comprise glass fibers. 5. The tethered flange corner of claim 1 wherein the fiber tow comprises carbon fiber. 6. The tethered flange corner of claim 1 wherein the fiber tow is wrapped about the barrier fibers from 3 to 6 times. 7. The tethered flange corner of claim 1 wherein more than one fiber tow is wrapped about the barrier fibers. 8. A flange having a tethered corner comprising: at least one ply of barrier fibers comprising a multidirectional fiber preform; at least one fiber tow wrapped circumferentially about the barrier fibers to produce the tethered flange corner; at least one ply of filler fibers applied over the fiber tow; and at least one ply of flange fibers applied over the filler fibers. 9. The flange of claim 8 wherein the flange is selected from the group consisting of end flanges, mounting flanges and combinations thereof. 10. The flange of claim 8 wherein the filler fibers are comprised of a material selected from the group consisting of glass fibers, graphite fibers, carbon fibers, ceramic fibers, aromatic polyamide fibers, and combinations thereof. 11. The flange of claim 8 wherein the flange fibers are comprised of a material selected from the group consisting of glass fibers, graphite fibers, carbon fibers, ceramic fibers, aromatic polyamide fibers, and combinations thereof. 12. An article comprising: a composite structure including a flange having a tethered corner comprising: at least one ply of barrier fibers comprising a multidirectional fiber preform; and at least one fiber tow wrapped circumferentially about the barrier fibers to produce the tethered flange corner. 13. The article of claim 12 wherein the flange is selected from the group consisting of end flanges, mounting flanges and combinations thereof. 14. The article of claim 12 further comprising at least one ply of filler fibers applied over the fiber tow. 15. The article of claim 14 further comprising at least one ply of flange fibers applied over the filler fibers. 16. The article of claim 12 wherein more than one fiber tow is wrapped about the barrier fibers. 17. The article of claim 14 wherein the filler fibers are comprised of a material selected from the group consisting of glass fibers, graphite fibers, carbon fibers, ceramic fibers, aromatic polyamide fibers, and combinations thereof. 18. The article of claim 15 wherein the flange fibers are comprised of a material selected from the group consisting of glass fibers, graphite fibers, carbon fibers, ceramic fibers, aromatic polyamide fibers, and combinations thereof. 19. The article of claim 12 wherein the composite structure is a fan casing.
