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.
Claims36
A guide for a cutting instrument, the guide comprising:
- a base;
- at least one leg in communication with the base, and
- a guide slot extending longitudinally through the base, said guide slot defined by the leg and the base.
An apparatus comprising:
- a guide, said guide comprising a base, said base comprising at least one leg, said leg dimensioned to extend into a cellular core cell in an area, of a cellular core said cellular core cell comprising a plurality of cell walls, said guide comprising a guide slot defined by the leg and the base, said guide slot extending longitudinally within the guide;
- and
- a cutting instrument.
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;
- and
- inserting a cellular rework section plug into the cut-out cellular section, said cellular rework section plug comprising intact cells, said cells comprising an intact septum in each cell.
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 a 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 of an adjoining cell at a cell wall juncture.
