Thickness gradients in large, cobonded composite structures resulting from gravity-induced resin migration during curing is substantially reduced by rotating the structure during the resin infusion and curing stages. The layup for the structure is placed on a rotatable tool fixture and vacuum bagged. The tool fixture is mounted on a central support tube provided with motors for rotating the tool fixture about the axis of the tube. The tube has internal passageways that deliver resin to the bagged layup and carry away excess resin from the layup using vac...


1. A method of manufacturing a composite structure comprising the steps of: using a tool comprising a first tube, a motor connected to the first tube, and a support connected to the motor, to the first tube, and to a mold, wherein the mold is disposed around the first tube at a radial distance relative to the first tube, wherein the mold comprises an inside surface, wherein the motor is configured to rotate the first tube, the support, and the mold substantially continuously in an angular direction, wherein the tool further comprises a second tube extend...
