发明名称 Infusion joining of composite structures
摘要 A method of joining two components utilizes a fibrous preform at the joint. The preform has two lateral portions and a longitudinally extending flow path. The preform is sandwiched between the two components and enclosed within a vacuum bag. Resin is introduced at an inlet of the flowpath while a vacuum pump creates a suction at an outlet end and along the lateral side edges. The flow path has greater permeability than the remaining portions of the preform, causing the resin to flow to the outlet end. When the resin reaches the outlet end, the suction at the outlet end is reduced, but the suction at the lateral edges remains without reduction to cause the resin to flow laterally into the preform.
