Abstract: A composite component includes a honeycomb, a skin bonded to the honeycomb, a repair section bonded adjacent to the skin, and at least one cover secured on at least a portion of the repair section to resist peeling of the repair section.

Abstract: A method of restoring a section of a composite includes the steps of removing an undesirable section of a composite and securing a repair section in the location of the removed undesirable section. One or more covers are secured on at least a portion the repair section to prevent or resist peeling of the repair section.

Abstract: A method for repairing or replacing a mechanically retained vane is provided. The method comprises the steps of forming an oversized cavity in a support structure, inserting a flared end of a vane in the oversized cavity, and inserting a wedge for mechanically retaining the flared end of the vane in the oversized cavity.

Abstract: A method of determining a depth of intergranular attack (IGA) on a surface of a metal part includes applying a replicating material on a second surface of the part that is essentially perpendicular to and intersects with the surface of interest. The replicating material is used to create an inverted replica of the microstructure of the second surface. Lengths of the cracks replicated on the replicating material are measured in order to determine the depth of intergranular attack on the surface of the part. In some embodiments, a fixture device may be temporarily attached to the metal part to maintain an edge of the second surface.

Abstract: A method for inspecting a repair insert welded into a hole where the weld is not permitted to penetrate the full depth of the hole. An inspection feature, either grooves at the minimum and maximum weld depths or grooves parallel to the insert axis, is formed on the surface of the repair insert. The insert is welded into the hole using electron beam or laser welding. The structure is then non-destructively inspected to determine whether the inspection feature has been consumed at the minimum required weld depth and has not been consumed at the maximum permitted weld depth.
