Abstract: An assembly includes a fiber-reinforced composite structure, a bushing, and a fastener. The composite structure includes a composite panel on a first side, where the composite panel defines a hemispherical well. The structure further includes a plurality of stiffening ribs on a second side, which are affixed to the composite panel. The composite panel defines a first bore at the center of the hemispherical well, which extends through the structure. The bushing has a hemispherical end and a flat end, and defines a second bore from the center of the hemispherical end to the center of the flat end. The hemispherical end of the bushing is configured to nest within the hemispherical well defined by the composite structure such that the flat end of the bushing is flush with the surrounding composite panel. The fastener is configured to extend within both of the first bore and the second bore.
