Abstract

A decorative laminate panel comprises compressible objects embedded inside, wherein the compressible objects would be flattened in unnatural shapes under conventional processes. For example, an exemplary decorative laminate product comprises thatch reed, willow reed, bamboo, weeds, grasses, twigs and branches of a tree or bush, beans, and so forth. In at least one exemplary implementation of the present invention, an extruded sheet, such as PETG or polycarbonate, is softened and melted around the compressible materials such that the compressible materials do not deform. Imperfections in the decorative laminate panel can be easily removed, thereby allowing for producing a high quality decorative laminate panel with high efficiency and relatively low cost compared with conventional methods and materials.

Claims

1. A decorative architectural panel comprising:

one or more compressible objects suspended between two extruded resin sheets formed together about the one or more compressible objects using a plurality of pressures in a thermosetting process, at least one of the plurality of pressures being greater than or equal to a critical pressure sufficient to otherwise compress the one or more compressible objects to an unnatural appearing conformation;

wherein the one or more compressible objects maintain a substantially natural appearing conformation between the two formed resin sheets.

2. The panel as recited in claim 1, wherein the first and second extruded sheets are at least partially translucent.

3. The panel as recited in claim 1, wherein the decorative laminate panel has a thickness of between 0.25 and 2 inches.

4. The panel as recited in claim 1, wherein at least one of the first and second extruded sheets comprise extruded PETG having a thickness of between 0.1 inches and 0.50 inches.

5. The panel as recited in claim 1, wherein at least one of the first and second extruded sheets comprise extruded polycarbonate having a thickness of between 0.1 inches and 0.50 inches.

6. The panel as recited in claim 1, wherein at least one of the first and second extruded sheets has a width and length dimensions of approximately 3′

×

5′

approximately 4′

×

8°

, or approximately 5′

×

10′

.

7. The panel as recited in claim 1, wherein at least one of the first and second extruded sheets comprises a copolyester that has a melting point between 180°

F. and 230°

F. in a pressure range of up to 40 psi.

8. The panel as recited in claim 1, wherein the one or more compressible objects comprise any one or more of bamboo, beans, straw, a tree branch, a tree twig, a bush branch, a bush twig, or any other object having a natural diameter that is substantially compressed at a critical pressure between about 10 psi and about 100 psi.

9. The panel as recited in claim 1, wherein a viewable surface of the decorative laminate panel is substantially uniform from one end to the next such that no lakes or air bubbles are exposed.

10. The panel as recited in claim 1, wherein the one critical pressure is less than about 92 psi for the one or more compressible objects.

11. The panel as recited in claim 10, wherein the critical pressure is greater than about 10 psi, such that the one or more compressible three-dimensional objects ordinarily appear to have an unnatural conformation when subjected to the critical pressure of between about 10 psi and 92 psi.

12. The panel as recited in claim 10, wherein the unnatural appearance comprises a substantially flattened appearance for the one or more compressible three-dimensional objects when viewed through the first or second extruded sheet.

13. A laminate sheet assembly configured to create the decorative architectural panel recited in claim 1 when the laminate assembly is subjected to the plurality of pressures in the thermosetting process comprising:

the first extruded sheet;

the one or more three-dimensional objects arranged on the first extruded sheet; and

a second extruded sheet positioned about the one or more embedded objects;

wherein the one or more three-dimensional objects are arranged in a position between the first and second extruded sheet such that sufficient air escapes from between the embedded objects as pressure is increased, such that lakes or air bubbles are avoided when the first extruded sheet and second extruded sheet are formed together.

14. The laminate sheet assembly as recited in claim 13, further comprising a pressure pad positioned about one of the first and second extruded sheets.

15. The laminate sheet assembly as recited in claim 13, wherein the first and second extruded sheets comprise PETG.

16. The laminate sheet assembly as recited in claim 13, wherein the first and second extruded sheets comprise polycarbonate.

17. The decorative architectural panel as recited in claim 1, wherein the one or more compressible objects comprise thatch or willow reed.

18. The decorative architectural panel as recited in claim 1, wherein the one or more compressible objects comprise bamboo.

19. A decorative architectural resin panel comprising:

first and second extruded resin sheets formed together with a plurality of pressures, at least one of the one plurality of pressures being greater than a critical pressure at which one or more three-dimensional objects ordinarily collapse to a substantially unnatural conformation; and

an image layer positioned between the first and second extruded sheets that are formed together, the image layer comprising the one or more three-dimensional objects in a substantially natural conformation;

wherein the one or more three-dimensional objects of the image layer maintain an appearance of the substantially natural conformation despite having been subjected to the critical pressure.
