10. A method of fabricating a composite structure, comprising:
-
laying down a plurality of fibers in a first layer to form a composite spar, wherein the first layer has a first component that extends generally in a first plane and a second component that extends generally in a second plane and a third component that extends generally in a third plane such that a first transition zone between the first and second components extends in at least a first generally linear manner and such that a second transition zone between the second and third components extends in at least a second generally linear manner in a different direction than the first generally linear manner, wherein the method further comprises steering plies of the fibers of the first layer to be, at the first transition zone, effectively normal to the direction of extension of the first transition zone and to be, at the second transition zone, effectively normal to the direction of extension of the second transition zone. - View Dependent Claims (11, 12, 13, 14, 25)

15. A structural component, comprising:
a composite tapered wing spar having a web and two flanges on opposite sides of the web, the composite tapered wing spar having a first fiber layer made up of a plurality of plies that are effectively normal to directions of extensions of the respective flanges at respective transition zones of the flanges and web, wherein the directions of extensions of the respective flanges are obliquely angled relative to one another. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 24)
