Abstract
Methods for reworking structures and reworked cellular core panels, reworked structures comprising the reworked cellular core panels, and guides and cutting apparatuses for reworking cellular acoustic panels and reworking cellular non-acoustic panels are disclosed.
Claims19
A method comprising:
- removing a removable cellular section from a cellular core to form a cut-out cellular core, said cut-out cellular core comprising intact cells, said cells comprising an intact septum in each cell, said cut-out cellular core further comprising a cut-out cellular core geometry, said cut-out cellular core comprising a plurality of cell walls, with each cell wall severed from an adjoining cell wall of an adjoining cell at a cell wall juncture to form the cut-out cellular core;
- and
- inserting a cellular rework section plug into the cut-out cellular core, said cellular rework section plug comprising intact cells, said cells comprising an intact septum in each cell, said cellular rework section plug comprising a cellular rework section plug geometry, said cellular rework section plug comprising a plurality of cell walls, with said cellular rework section plug formed by severing completely an adjoining cell wall of an adjoining cell at a cell wall juncture to form the cellular rework section plug.
A method of cutting an area from a cellular core to form a removable cellular core section and a cut-out-cellular core section in the cellular core comprising:
- inserting a guide to a predetermined depth into the at least one cell of the cellular core;
- receiving a leg of the guide into at least one cell;
- inserting a cutting instrument into the guide;
- and
- severing a cell wall of the cell completely from an adjoining cell wall at a cell wall juncture to form at least one of:
- a cellular section rework plug or a cut-out cellular core section.
