Abstract
A method for repairing a crack in a structure includes mounting a manifold to the structure around the crack. The structure has a nonplanar surface contour that surrounds the crack. The manifold has a base portion, a cover portion, and a plug. The base portion has a grip surface configured to conform to the nonplanar surface contour of the structure. The cover portion is connected to the base portion, and has an injection port and a vent port in fluid communication with a channel aligned to the crack. The injection port transfers a bonding material into and out of the channel. The plug closes and opens the vent port. The method includes filling the channel with the bonding material to direct the bonding material into the crack, and draining the bonding material from the manifold.
