ABSTRACT:
A composite structure is fabricated by providing a mandrel having a winding surface and placing a shaped plug into the winding surface so that it extends from the winding surface. An uncured composite material is wound over the winding surface of the mandrel and laterally adjacent to the shaped plug. The composite material is cured, and the shaped plug and mandrel are removed. The shaped plug may be provided with an overlying bushing that is bonded to the composite material during curing and is not removed with the remainder of the shaped plug.
