A method for repairing a sandwich composite structure comprising a pinned foam core. In the sub-region in which the pinned foam core is damaged, the at least one upper or lower cover layer is removed as far as the pinned foam. The pinned foam core is removed. A pinned replacement foam core is inserted, the pinned replacement foam core being impregnated with a resin. An upper or lower replacement cover layer is applied. The pinned replacement foam core and optionally the upper or lower replacement cover layer are cured.

A tire repair tool assembly includes a tool body, at least one tire plug, a plug storage cap, and a hollow tube. The tool body may have a first end and a second end opposite the first end, the tool body having a storage compartment within the tool body, the storage compartment having an opening at the first end. The plug storage cap may be operably coupled to the first end of the tool body. The hollow tube may be sized to receive a first end of the at least one tire plug within the hollow tube, the hollow tube extending from the second end of the tool body and having a tip distal from the second end of the tool body. The tire repair assembly may further include a tool body case having a closed end and an open compartment within the tool body case.

An acoustic honeycomb panel is plugged with an acoustic honeycomb plug. The acoustic honeycomb plug is adhesively bonded in the panel using a honeycomb seam. The honeycomb seam is composed of a honeycomb support that is located within the seam channel and an adhesive. Using honeycomb seams to adhesively bond acoustic honeycomb plugs into acoustic honeycomb panels is useful in repairing damaged areas of acoustic honeycomb panels that are located in the acoustic treatments for jet engines.
