Systems and methods for creating a honeycomb core with venting pathways
A method for creating a honeycomb core having venting pathways includes controlling where a resin is applied to sheets by creating a resin affinity portion and a resin repellant portion on the sheets. The resin affinity portion and the resin repellant portion forms the venting pathways. A honeycomb substrate is then formed from the sheets.
1. A method for creating a honeycomb core having venting pathways formed therethrough, the method comprising:
controlling where a resin is applied to sheets by creating a resin affinity portion and a resin repellant portion on the sheets;
degrading the resin repellant portion to form the venting pathways through the honeycomb core;
forming a honeycomb substrate from the sheets; and
applying the resin to the honeycomb substrate to form the honeycomb core.
2. The method of claim 1 , wherein degrading the resin repellant portion to form venting pathways through the honeycomb core includes at least one of washing the resin repellant portion in a solvent, thermally degrading the resin repellant portion, or gravity floating the resin repellant portion.
3. The method of claim 1 , wherein creating the resin affinity portion and the resin repellant portion on the sheets includes applying a resin repellant to the sheets.
4. The method of claim 3 , wherein applying the resin repellant to the sheets includes printing the resin repellant on the sheets.
5. The method of claim 3 , wherein applying a resin repellant to the sheets includes coating the sheets with the resin repellant.
6. The method of claim 1 , wherein creating the resin affinity portion and the resin repellant portion on the sheets includes applying a resin affinity material to the sheets.
7. The method of claim 6 , wherein the sheets are comprised of a resin repellant material.
8. The method of claim 6 , wherein applying the resin affinity material to the sheets includes printing the resin affinity material on the sheets.
9. The method of claim 6 , wherein applying the resin affinity material to the sheets includes coating the sheets with the resin affinity material.
10. A method for creating a honeycomb core having venting pathways formed therethrough, the method comprising:
applying a resin repellant to sheets to form a resin affinity portion and a resin repellant portion on the sheets;
forming a honeycomb substrate from the sheets; and
applying a resin to the honeycomb substrate to form the honeycomb core, wherein the resin repellant portion forms the venting pathways.
11. The method of claim 10 , wherein the sheets are comprised of a resin affinity material.
12. The method of claim 10 , wherein applying the resin repellant to the sheets includes printing the resin repellant on the sheets.
13. The method of claim 12 , wherein printing the resin repellant on the sheets includes at least one of digital printing, screen printing, lithography printing, flexography printing, and offset printing.
14. The method of claim 10 , wherein applying a resin repellant to the sheets includes coating the sheets with the resin repellant.
15. The method of claim 14 , wherein coating the sheets with the resin repellant includes at least one of coating using a mesh screen coater and coating using a rotary screen coater.
16. The method of claim 10 , wherein applying the resin repellant to the sheets includes applying the resin repellant to the sheets in a repeating pattern on selective areas of the sheets.
17. A method for creating a honeycomb core having venting pathways formed therethrough, the method comprising:
applying a resin affinity material to sheets to form a resin affinity portion and a resin repellant portion on the sheets;
forming a honeycomb substrate from the sheets; and
applying a resin to the honeycomb substrate to form the honeycomb core, wherein the resin repellant portion forms the venting pathways.
18. The method of claim 17 , wherein the sheets are comprised of a resin repellant material.
19. The method of claim 17 , wherein applying the resin affinity material to the sheets includes printing the resin affinity material on the sheets.
20. The method of claim 19 , wherein printing the resin affinity material on the sheets includes at least one of digital printing, screen printing, lithography printing, flexography printing, and offset printing.
21. The method of claim 17 , wherein applying the resin affinity material to the sheets includes coating the sheets with the resin affinity material.
22. The method of claim 21 , wherein coating the sheets with the resin affinity material includes at least one of coating using a mesh screen coater and coating using a rotary screen coater.
23. The method of claim 17 , wherein applying the resin affinity material to the sheets includes applying the resin affinity material to the sheets in a repeating pattern on selective areas of the sheets.
