Abstract
A method for the repair of a sandwich plate having a core structure, a top surface layer and a bottom surface layer and a plurality of honeycomb-shaped cells includes providing at least one penetrating drill hole in at least one of the top surface layer and the bottom surface layer above one of the plurality of honeycomb-shaped cells in a damaged region of the sandwich plate, injecting a stabilising material into the honeycomb-shaped cell, and filling the damaged region with a filler material.
Claims13
A method for the repair of a sandwich plate having a core structure, a top surface layer and a bottom surface layer and a plurality of honeycomb-shaped cells, the method comprising:
- providing at least one penetrating drill hole in at least one of the top surface layer and the bottom surface layer near to one of the plurality of honeycomb-shaped cells in a damaged region of the sandwich plate;
- injecting a stabilising material into the honeycomb-shaped cell;
- and
- filling the damaged region with a filler material.
A spraying device for a repair of a sandwich plate having a core structure, a top surface layer and a bottom surface layer and a plurality of honeycomb-shaped cells, the device comprising:
- a reservoir filled with stabilising material based on one component;
- a spraying tube, wherein the reservoir is configured to dispense the stabilising material into the spraying tube;
- and
- a nozzle disposed downstream of the spraying tube and configured to atomize the stabilising material so as to form a spray mist.
A spraying device for a repair of a sandwich plate having a core structure, a top surface layer and a bottom surface layer and a plurality of honeycomb-shaped cells, the device comprising:
- a first reservoir containing a first component and configured to evenly dispense the first component;
- a second reservoir containing a second component different from the first component and configured to evenly dispense the second component;
- and
- a Y-section connecting the first reservoir to the second reservoir.
