초록 ▼

A corner fitting and a method of forming a corner fitting including steps of providing a flat woven fabric including a first woven portion having first and second direction woven fibers, a second woven portion adjacent the first woven portion having first direction fibers and sacrificial second direction fibers and a third semi-woven portion having first direction fibers selectively engaged by the sacrificial second direction yarns. The method further comprising steps of folding the flat woven fabric in at least one direction, and removing the sacrificial second direction fibers, wherein during removal, the sacrificial second direction fibers are replaced in the second woven portion by the first direction fibers of the third semi-woven portion and form a corner fitting having continuous fibers connecting all sides.

대표청구항 ▼

What is claimed is: 1. A corner fitting formed out of a folded flat woven fabric comprising: a first woven portion having first and second direction woven fibers; a second woven portion adjacent the first woven portion having first direction fibers and sacrificial second direction fibers; and a third semi-woven portion having first direction fibers selectively engaged by the sacrificial second direction fibers, wherein upon removal of said sacrificial second direction fibers, said first direction fibers of said third semi-woven portion replace the sacrificial second direction yarns of said second woven portion and form a corner fitting having continuous fibers connecting all sides. 2. The corner fitting of claim 1 wherein the first direction fibers are warp fibers, the second direction fibers are weft fibers and the sacrificial second direction fibers are weft fibers. 3. The corner fitting of claim 1, wherein the flat woven fabric is a multi-layer fabric. 4. The corner fitting of claim 1, wherein the first and second direction fibers are selected from the group consisting of glass, carbon, ceramic, aramid, and polyethylene fibers. 5. The corner fitting of claim 1, wherein the first and second direction fibers are encased in a matrix material which creates a composite. 6. The corner fitting of claim 1, which is integrated into a larger preform or structure. 7. The corner fitting of claim 6, wherein said larger preform or structure is encased in a matrix material which creates a composite. 8. A method of forming a corner fitting comprising the steps of: providing a flat woven fabric including a first woven portion having first and second direction woven fibers, a second woven portion adjacent the first woven portion having first direction fibers and sacrificial second direction fibers and a third semi-woven portion having first direction fibers selectively engaged by the sacrificial second direction fibers; folding said flat woven fabric in at least one direction; and removing said sacrificial second direction fibers, wherein during removal said sacrificial second direction fibers are replaced in said second woven portion by the first direction fibers of the third semi-woven portion and form a corner fitting having continuous fibers connecting all sides. 9. The method of claim 8, further comprising a step of encasing the first and second direction fibers in matrix material which creates a composite. 10. The method of claim 8 further comprising a step of cutting portions of the first direction fibers of the third semi-woven portion extending past an end of said second woven portion after removal of the sacrificial second direction fibers of said second woven portion. 11. The method of claim 10, further comprising a step of trimming a portion of said second woven portion. 12. The method of claim 8 wherein the first direction woven fibers are warp yarns, the second direction fibers are weft fibers and the sacrificial second direction fibers are weft fibers. 13. The method of claim 8, wherein the flat woven fabric is a multi-layer fabric. 14. The method of claim 8, further comprising a step of selecting the first and second direction fibers from the group consisting of glass, carbon, ceramic, aramid, and polyethylene fibers. 15. The method of claim 8 wherein said corner fitting is included into a larger preform or structure. 16. The method of claim 15 wherein said larger preform or structure is encased in a matrix material which creates a composite.
