Panel structure with scored and folded facing
View Patent ↗A panel structure having a low-density core that can withstanding loads normal to a first primary surface, and a first facing of high-density sheet material that can extend along the first primary surface. The high-density sheet material can be laminated on the core such that the laminated core and facing cooperatively resist bending loads and loads along the primary surface. The first facing can extend from the first primary surface on a side of the core along a secondary surface, which can be non-parallel to the first primary surface. The first facing can bend along a score line between the first primary surface and the secondary surface.
1. A method of making a panel structure, comprising:
providing a laminate that includes:
a high-density first facing, and
a low-density core configured for withstanding loads normal to a first primary surface, the core laminated to the first facing along a first primary surface in an association that cooperatively resists bending loads, and loads along the first primary surface;
cutting through the low-density core sufficiently deeply to simultaneously score the first facing, thereby creating a first score line between a first portion and a second portion of the first facing and removing a portion of the core from the second portion of the first facing so that the second portion of the first facing extends beyond the remaining portion of the laminated core;
creating a second score line between the second portion and a third portion of the first facing; and
bending the third portion of the first facing with respect to the second portion of the facing along the second score line to produce a bend such that the third portion of the facing extends along a second primary surface of the core that is opposite to the first primary surface.
2. The method of claim 1 , further comprising bending the second portion of the first facing with respect to the first portion of the facing along the first score line such that the second portion extends on a side of the core along a secondary surface that is non-parallel to the first primary surface.
3. The method of claim 2 , further comprising laminating the bent second portion to the remaining portion of the core.
4. The method of claim 3 , wherein the bent second portion is laminated onto the secondary surface of the core.
5. The method of claim 1 , further comprising laminating the third portion onto a second facing on the second primary surface.
6. The method of claim 1 , wherein
the second score line is spaced from and parallel to the first score line at a distance substantially equal to a thickness of a secondary surface that is non-parallel to the first and second primary surfaces.
7. The method of claim 6 , wherein the laminated structure includes a high-density second facing laminated on the second primary surface, the method further comprising laminating the third portion to the second facing.
8. The method of claim 1 , further comprising laminating the first portion of the first facing onto the core to provide a laminated structure.
9. The method of claim 1 , wherein the step of cutting includes using a cutting element, and the cutting element is a single cutter.
10. The method of claim 1 , wherein the first facing and core are made of a paper material.
11. The method of claim 1 , wherein the first facing is a multilayered sheet material.
12. The method of claim 1 , wherein the core comprises a honeycomb material.
13. The method of claim 1 , wherein the high-density facing comprises a material having less than about 10% airspace and the low-density core comprising a material having more than about 70% airspace.
14. The method of claim 1 , wherein the high-density first facing has substantially no air space.
15. A method of making a panel structure, comprising:
providing a laminate that includes:
a high-density first facing;
a low-density core configured for withstanding loads normal to a first primary surface, the core laminated to the first facing along a first primary surface in an association that cooperatively resists bending loads and loads along the first primary surface;
cutting through the low-density core sufficiently deeply to simultaneously score the first facing, creating a first score line between a first portion and a second portion of the first facing;
removing the cut-off portion of the core from the remaining portion of the core and the second portion of the first facing so that the second portion of the first facing extends beyond the remaining portion of the laminated core;
bending the second portion of the first facing with respect to the first portion of the facing along the first score line to produce a bend such that the second portion extends on a side of the core along a secondary surface that is non-parallel to the first primary surface; and
laminating the second portion onto the secondary surface of the core.
16. The method of claim 15 , further comprising laminating the first portion of the first facing onto the core to provide a laminated structure.
17. The method of claim 15 , wherein the first facing includes a third portion, the method further comprising:
scoring a second score line between the second and third portions of the first facing; and
bending the third portion of the first facing with respect to the second portion of the facing along the second score line to produce a bend such that the third portion of the facing extends along a second primary surface of the core that is opposite to the first primary surface.
18. The method of claim 17 , wherein the laminated structure includes a high-density second facing laminated on the second primary surface, the method further comprising laminating the third portion to the second facing.
19. The method of claim 17 , wherein the second score line is spaced from and parallel to the first score line at a distance substantially equal to a thickness of a secondary surface that is non-parallel to the first primary surface.
20. The method of claim 15 , wherein the cutting includes using a single cutting element.
21. A method of making a panel structure, comprising:
cutting through a low-density core of a laminate sufficiently deeply to simultaneously score a high-density first facing of the laminate, thereby creating a first score line between a first portion and a second portion of the first facing, the core configured for withstanding loads normal to a first primary surface, the core laminated to the first facing along the first primary surface in an association that cooperatively resists bending loads and loads along the first primary surface;
removing a portion of the core so that the second portion of the first facing extends beyond the remaining portion of the laminated core;
bending the second portion of the first facing with respect to the first portion of the facing along the first score line such that the second portion extends on a side of the core along a secondary surface that is non-parallel to the first primary surface; and
laminating the bent second portion to the remaining portion of the core.
22. The method of claim 21 , further comprising:
creating a second score line between the second portion and a third portion of the first facing; and
bending the third portion of the first facing with respect to the second portion of the facing along the second score line to produce a bend such that the third portion of the facing extends along a second primary surface of the core that is opposite to the first primary surface.
23. The method of claim 22 , further comprising laminating the bent third portion to the second primary surface.
24. The method of claim 23 , wherein the second primary surface is a surface of a high-density second facing.
25. The method of claim 21 , wherein the core comprises a honeycomb material.
