A method of repairing an aircraft component having a structural core surrounded by an exterior skin of composite material includes removing damaged material from the component to create a cavity therein that exposes an undamaged portion of the structural core, applying a septum comprising composite material to the undamaged portion of the structural core within the cavity such that an orientation of fibers in the septum matches an orientation of fibers in the exterior skin, placing a repair core onto the septum in the cavity such that cells of the repair core are in alignment with cells of the undamaged portion of the structural core, inserting a shim into the cavity along a perimeter of the repair core, applying a patch that covers the cavity to the exterior skin, and co-curing the septum, shim, and patch to bond the repair core in place within the cavity.

A bond fixture includes a frame defining a chamber for receiving a component. At least one bladder assembly is connected to the frame. The at least one bladder assembly includes a pad for contacting the component. A position of the pad relative to the component is controlled by a pressure of the bladder assembly. A caul assembly is adapted to thermally couple to the component to heat a localized portion of the component.

A system (50) and method (200) for repairing one or more components (70) using an additive manufacturing process includes securing the components (70) in a tooling assembly (52) such that a repair surface (72) of each component (70) is positioned within a single build plane (82), determining a repair toolpath (76) corresponding to the repair surface (72) of each component using a vision system (56), depositing a layer of additive powder (72) over the repair surface (72) of each component (70) using a powder dispensing assembly (112), and selectively irradiating the layer of additive powder (72) along the repair toolpath (76) to fuse the layer of additive powder (72) onto the repair surface (72) of each component (70).

A puncture repair fluid container includes: a container body including a storage portion for storing a puncture repair fluid and an opening portion provided at one end of the storage portion; and a cap mounted to the opening portion. The cap includes an introduction path for introducing compressed air from outside; a discharge path for discharging the puncture repair fluid to the outside; a switching valve for switching two paths disposed between the introduction path and the discharge path; and a switching knob for operating the switching valve. A jig for rotating the switching knob is provided, the switching knob is provided with a recessed portion or protruding portion, and the jig is configured to be attachable and detachable to the switching knob, the jig being provided with a protruding portion or recessed portion that is fitted in or to the recessed portion or protruding portion of the switching knob.

A tooling assembly and method of aligning a plurality of components for a repair process in an additive manufacturing machine includes positioning the plurality of components such that a repair surface of each of the plurality of components contacts an alignment plate, e.g., under the force of gravity or using biasing members. The method further includes surrounding the alignment plate with containment walls to define a reservoir around the plurality of components and dispensing a fill material, such as wax or a potting material, into the reservoir which is configured for fixing a relative position of the plurality of components when the fill material is solidified.

Methods of additively printing an extension segment on a workpiece may include pretreating a workpiece-interface of a workpiece using an energy beam from an additive manufacturing machine, providing a pretreated workpiece-interface having received a pretreatment, with the pretreatment remediating an aberrant feature of the workpiece and/or the workpiece-interface. Such methods may additionally include additively printing an extension segment on the pretreated workpiece-interface using the energy beam from the additive manufacturing machine. Exemplary additive manufacturing system for printing an extension segment on a workpiece may include a controller operably coupled to a vision system and an additive manufacturing machine.

A method of repairing a composite structure includes providing an assembled composite structure comprising a substantially rigid outer component, wherein the composite structure comprises a void space at least partially bounded by the outer component. The method further includes forming an injection hole through the outer component to provide a path between the void space and space external to the composite structure. The method further includes injecting foam into the void space through the injection hole while the foam is in a substantially unexpanded state and expanding the foam within the void space.
