Abstract

A panel assembly that includes a front skin having a front surface, a back surface and at least one crush section portion, a core assembly that includes first, second, third, fourth and fifth layers laminated together, and at least a first crush section. The first, second, third, fourth and fifth layers each include a front surface, a back surface and at least one crush section portion. The front surface of the first layer of the core assembly includes a plurality of scores defined therein. The second layer includes a plurality of elongated voids defined therein and the fourth layer includes a plurality of elongated voids defined therein.

First claim

What is claimed is:

1. A panel assembly comprising:
a front skin having a front surface, a back surface and at least one crush section portion,
a core assembly that includes first, second, third, fourth and fifth layers laminated together,
a first crush section, and
a second crush section,
wherein the first layer has a front surface, a back surface and at least one crush section portion, wherein the second layer has a front surface, a back surface and at least one crush section portion, wherein the front surface of the second layer is bonded to the back surface of the first layer, wherein the third layer has a front surface, a back surface and at least one crush section portion, wherein the front surface of the third layer is bonded to the back surface of the second layer, wherein the fourth layer has a front surface, a back surface and at least one crush section portion, wherein the front surface of the fourth layer is bonded to the back surface of the third layer, wherein the fifth layer has a front surface, a back surface and at least one crush section portion, and wherein the front surface of the fifth layer is bonded to the back surface of the fourth layer,
wherein the front surface of the first layer includes a plurality of scores defined therein, wherein the second layer includes a plurality of elongated voids defined therein, and wherein the fourth layer includes a plurality of elongated voids defined therein,
wherein, within the second crush section, the front surface of the first layer of the core assembly includes a plurality of scores defined therein, wherein the second layer includes a plurality of elongated voids defined therein, and wherein the fourth layer includes a plurality of elongated voids defined therein, and
wherein the first crush section and the second crush section are separated horizontally by a non-crush section.

2. The panel assembly of claim 1 wherein within the first crush section, the front skin includes a first cut pattern that comprises a plurality of horizontal and vertical cuts formed therein.

3. The panel assembly of claim 2 wherein the plurality of horizontal and vertical cuts form a plurality of rows and columns.

4. The panel assembly of claim 3 wherein each row includes alternating horizontal and vertical cuts.

5. The panel assembly of claim 4 wherein each column includes alternating horizontal and vertical cuts.

6. The panel assembly of claim 5 wherein the front skin includes a glass weave layer and a surface finish layer, and wherein the horizontal and vertical cuts are made in the glass weave layer.

7. The panel assembly of claim 1 wherein the plurality of scores in the front surface of the first layer are positioned within the crush section portion.

8. The panel assembly of claim 7 wherein the plurality of scores in the front surface of the first layer extend generally parallel to one another.

9. The panel assembly of claim 8 wherein the plurality of scores in the front surface of the first layer extend generally horizontally.

10. The panel assembly of claim 1 wherein the plurality of elongated voids in the fourth layer are staggered vertically from the plurality of elongated voids in the second layer.

11. The panel assembly of claim 2 further comprising at least a first extended crush section that includes a second cut pattern that comprises a plurality of horizontal and vertical cuts formed therein, and wherein the horizontal and vertical cuts of the second cut pattern are not as dense as the horizontal and vertical cuts in the first cut pattern.

12. A panel assembly comprising:
a front skin having a front surface, a back surface and at least one crush section portion, wherein within the at least one crush section portion, the front skin includes a cut pattern that comprises a plurality of horizontal and vertical cuts formed therein, wherein the plurality of horizontal and vertical cuts form a plurality of rows and columns, wherein each row includes alternating horizontal and vertical cuts, and wherein each column includes alternating horizontal and vertical cuts,
a core assembly that includes first, second, third, fourth and fifth layers laminated together,
a first crush section, and
a second crush section,
wherein the first layer has a front surface, a back surface and at least one crush section portion, wherein the second layer has a front surface, a back surface and at least one crush section portion, wherein the front surface of the second layer is bonded to the back surface of the first layer, wherein the third layer has a front surface, a back surface and at least one crush section portion, wherein the front surface of the third layer is bonded to the back surface of the second layer, wherein the fourth layer has a front surface, a back surface and at least one crush section portion, wherein the front surface of the fourth layer is bonded to the back surface of the third layer, wherein the fifth layer has a front surface, a back surface and at least one crush section portion, and wherein the front surface of the fifth layer is bonded to the back surface of the fourth layer,
wherein the front surface of the first layer includes a plurality of horizontally extending scores defined within the crush section portion,
wherein the second layer includes a plurality of elongated voids defined therein, wherein the fourth layer includes a plurality of elongated voids defined therein, wherein the plurality of elongated voids in the fourth layer are staggered vertically from the plurality of elongated voids in the second layer,
wherein, within the second crush section, the front surface of the first layer of the core assembly includes a plurality of scores defined therein, wherein the second layer includes a plurality of elongated voids defined therein, and wherein the fourth layer includes a plurality of elongated voids defined therein,
wherein the first crush section and the second crush section are separated horizontally by a non-crush section.

13. The panel assembly of claim 12 wherein the front skin includes a glass weave layer and a surface finish layer, and wherein the horizontal and vertical cuts are made in the glass weave layer.

14. A panel assembly comprising:
a front skin having a front surface, a back surface and at least one crush section portion,
a core assembly that includes at least a first layer, and
a first crush section, and
an extended crush section,
wherein the first layer has a front surface, a back surface and at least one crush section portion, wherein the front surface of the first layer includes a plurality of scores defined therein,
wherein, within the first crush section, the front skin includes a first cut pattern that comprises a plurality of horizontal and vertical cuts formed therein,
wherein the extended crush section includes a second cut pattern that comprises a plurality of horizontal and vertical cuts formed therein, and wherein the horizontal and vertical cuts of the second cut pattern are not as dense as the horizontal and vertical cuts in the first cut pattern.

15. The panel assembly of claim 14 wherein the plurality of horizontal and vertical cuts form a plurality of rows and columns.
