초록 ▼

Fiber reinforced composite structures having curved stepped surfaces are fabricated by laying up plies of fiber reinforced material over a tool having a stepped tool feature. The plies are rotated about a fixed axis as they are laid up to substantially form a fixed axis rosette pattern. The plies are angularly oriented such that at least certain of the plies have fiber orientations other than 0, +45, −45 and 90 degrees. Potential bridging of the fibers over the stepped tool features is reduced or eliminated by cutting slits in the plies in the area of the stepped features, so that the plies can be fully compacted.

1. A method of fabricating a fiber reinforced composite structure having a curved stepped surface, comprising the steps of: laying up a plurality of fiber reinforced material plies in a fixed axis rosette pattern over a tool having a curved stepped tool surface for forming a curved joggle, a curvature of the stepped tool surface comprising a compound curvature including an S-shaped curvature in a direction substantially parallel to a direction of a step comprising the curved stepped tool surface;forming an opening in each of the plurality of fiber reinforced material plies in an area of the curved stepped surface where fibers in the plurality of fiber reinforced material plies cross and bridge the curved joggle such that the opening is oriented in a direction perpendicular to axes of orientation of fibers for the plurality of fiber reinforced material plies; and,consolidating the plurality of fiber reinforced material plies. 2. The method of claim 1, wherein forming the opening includes forming a slit in each of the plurality of fiber reinforced material plies beginning at an edge of the curved stepped tool surface. 3. The method of claim 1, wherein forming the opening includes forming slits in the plurality of fiber reinforced material plies in the area of the curved stepped tool surface. 4. The method of claim 1, wherein laying up includes orienting the plurality of fiber reinforced material plies relative to each other about the fixed axis as the plurality of fiber reinforced material plies are being laid up. 5. The method of claim 1, wherein laying up includes orienting at least certain of the plurality of fiber reinforced material plies such that fiber orientations in at least certain plies are disposed at angles other than 0, +45, −45 and 90 degrees. 6. A method of fabricating a composite structure reinforced with fibers and having a curved stepped feature, comprising the steps of: arranging at least certain of a plurality of composite plies having the fibers over a tool having a stepped tool surface such that at least certain fibers bridge over the curved stepped feature, a curvature of the stepped tool surface comprising a compound curvature including an S-shaped curvature in a direction substantially parallel to a direction of a step comprising the tool, wherein arranging results in a curved joggle in the plurality of composite plies;cutting the certain fibers in an area of the curved stepped feature where fibers in the plurality of composite plies cross and bridge the curved joggle to form openings such that the openings are oriented in a direction perpendicular to axes of orientation of fibers for the plurality of composite plies; and,compacting the plurality of composite plies. 7. The method of claim 6, wherein cutting includes forming at least one slit in the plurality of composite plies. 8. The method of claim 6, wherein arranging includes orienting the plurality of composite plies relative to each other about a fixed axis as the plurality of composite plies are being arranged over the tool. 9. The method of claim 8, wherein the plurality of composite plies are oriented such that a fiber direction in at least certain of the plurality of composite plies are disposed at angles other than 0, +45, −45 and 90 degrees. 10. The method of claim 6, wherein arranging includes orienting the plurality of composite plies relative to each other about a fixed axis such that the openings are angularly spaced from each other about the fixed axis.
